The @or-sdk/qna package provides a client for working with the QnA (Question and Answer) system in OneReach.ai a.k.a Lookup. With this client, you can perform operations such as loading documents, creating collections, searching in collections, asking questions to generate answers based on the loaded documents, and managing properties of collections.
A collection is a group of searchable items, also known as passages. It allows you to organize and manage related documents and their passages together under a single entity. When you perform a search or ask a question, the QnA system will search through the passages within the specified collection.
Documents are used to load a bulk of data into a collection. They can be any type of text-based file such as PDFs, text files, or web pages. When you provide a URL for a document, the QnA system downloads the content, splits it into smaller chunks (passages), and adds them to the collection.
A passage is an atomic piece of data that represents a portion of a document. It is the smallest searchable unit within a collection. When you search or ask a question, the QnA system uses vector similarity to find the most relevant passages from all the documents in the collection.
The search process involves comparing the vector representation of the input query (search term or question) with the vector representations of the passages in the collection. The results are ranked based on the similarity between the query and passages, with the most similar passages being returned as the search results.
A property is an additional piece of information that can be added to a collection to store custom metadata about the collection. Properties can have a name, datatype, and an optional description. You can manage properties by adding, updating, or deleting them from a collection.
To install the package, run the following command:
$ npm install @or-sdk/qna
To use the QnA client, you need to create an instance of the class with the appropriate configuration options. You can either provide the direct API URL or the service discovery URL. Here is an example:
import { QnA } from '@or-sdk/qna';
// with direct api url
const qna = new QnA({
token: 'my-account-token-string',
serviceUrl: 'http://example.qna/endpoint'
});
// with service discovery(slower)
const qna = new QnA({
token: 'my-account-token-string',
discoveryUrl: 'http://example.qna/endpoint'
});
Once you have an instance of the QnA client, you can use its methods to interact with the OneReach.ai QnA system. The available methods are:
loadDocumentLoads a document into a collection by providing a URL to the document. The document can be in PDF, CSV, or HTML format. The QnA system downloads the content, splits it into smaller chunks called passages, and adds them to the collection. For CSV files, the primary data source is the content column, and additional columns can be matched to custom properties in the collection schema. The loading process is asynchronous, and the document status can be used to check if the loading is in progress or if an error occurred.
collectionId: string - The ID of the collection the document will be loaded intoparams: LoadDocument - Document loading parameters
description: string (optional) - Document descriptionurl: string - The URL of the document to loadname: string - Document namedefaultProperties: Record<string, unknown> (optional) - Default custom properties for the document passages. Note that these properties should be listed in the collection properties.The status field is used to identify the document loading progress and possible errors. The possible status values are:
NEW - The document has been created, but the loading process has not started yet.LOADING - The document loading is in progress.READY - The document loading has been completed successfully.ERROR - An error occurred during the document loading process due to unknown reasons.string - If a specific error occurred during the loading process, the error message will be provided in the status field.In this example, the loadDocument method downloads a document from the provided URL, splits the content into passages, and adds them to the specified collection. Additionally, the defaultProperties attribute is used to set custom properties for the passages.
const collectionId = 'a1b2c3d4-uuid';
const document = await qna.loadDocument(collectionId, {
name: 'Sample Document',
description: 'A sample document',
url: 'http://example.com/sample-document.pdf',
defaultProperties: {
author: 'John Doe',
publishDate: '2020-12-31'
}
});
// Example response
{
id: 'e5f6g7h8-uuid',
accountId: 'i9j0k1l2-uuid',
collection: 'a1b2c3d4-uuid',
name: 'Sample Document',
description: 'A sample document',
status: 'LOADING'
}
After the document loading process, the status will update according to the result:
// Example response when the document loading is successful
{
id: 'e5f6g7h8-uuid',
accountId: 'i9j0k1l2-uuid',
collection: 'a1b2c3d4-uuid',
name: 'Sample Document',
description: 'A sample document',
status: 'READY'
}
// Example response when there is an error during the document loading
{
id: 'e5f6g7h8-uuid',
accountId: 'i9j0k1l2-uuid',
collection: 'a1b2c3d4-uuid',
name: 'Sample Document',
description: 'A sample document',
status: 'Could not load the document due to an error...'
}
To handle cases where you need to wait for the document to fully load, you can use polling. Here's an example:
import { sleep } from 'utils';
async function waitForDocumentLoading(collectionId: string, documentId: string) {
let document;
let isLoading = true;
while (isLoading) {
document = await qna.getDocument(collectionId, documentId);
if (document.status === 'READY' || typeof document.status === 'string') {
isLoading = false;
} else {
await sleep(5000); // Wait for 5 seconds before checking the status again
}
}
return document;
}
async function loadDocumentAndWait(collectionId: string, documentParams: LoadDocument) {
const document = await qna.loadDocument(collectionId, documentParams);
const loadedDocument = await waitForDocumentLoading(collectionId, document.id);
return loadedDocument;
}
// Example usage
const collectionId = 'a1b2c3d4-uuid';
const documentParams = {
name: 'Sample Document',
description: 'A sample document',
url: 'http://example.com/sample-document.pdf',
defaultProperties: {
author: 'John Doe',
publishDate: '2020-12-31'
}
};
const loadedDocument = await loadDocumentAndWait(collectionId, documentParams);
console.log('Loaded document:', loadedDocument);
In this example, the loadDocumentAndWait function first calls the loadDocument method to start loading a document and then uses the waitForDocumentLoading function to poll for the document's status until it's either READY or an error message is provided. The sleep function is used to introduce a delay before checking the status again.
createCollectionCreates a new collection with optional properties. A collection is a group of related documents that are searchable together. Additional custom properties can be defined to store metadata associated with the documents within the collection.

],
}
Note: The custom properties defined for the collection can be used for filtering, sorting, and selecting specific properties when performing search or ask operations.
addPropertyAdd a custom property to an existing collection. Custom properties can be used to store additional metadata about the collection or its passages. The available data types for properties can be found at https://weaviate.io/developers/weaviate/config-refs/datatypes. Note that there are reserved property names ['accountId', 'collection', 'document', 'content', 'loaderMetadata', 'sourceUrl']
collectionId (string): The ID of the collection to which the property will be added.property (Property): The property to be added, which includes:
name (string): The name of the property, e.g. nameOfTheAuthor. Name should not include any space.dataType (string): The data type of the property. See https://weaviate.io/developers/weaviate/config-refs/schema#datatypes for the available typesdescription (string, optional): An optional description of the property.const collectionId = 'a1b2c3d4-uuid';
const property = {

await qna.addProperty(collectionId, property);
// No direct response, the property is added to the collection
You can verify the added property by retrieving the collection:
const collection = await qna.getCollection(collectionId);
// Example response
{
id: 'a1b2c3d4-uuid',
accountId: 'i9j0k1l2-uuid',
name: 'Sample Collection',
description: 'A sample collection',
countPassages: 42,
properties: [
{
name: 'author',
dataType: 'string',
description: 'Author of the document',
},
],
}
deleteCollectionDelete a collection by its ID. This operation will permanently remove the collection along with all the documents, passages, and custom properties associated with the collection.
string - The ID of the collection to deleteconst collectionId = 'a1b2c3d4-uuid';
await qna.deleteCollection(collectionId);
Note: Use this operation with caution, as deleting a collection is an irreversible action. Once a collection is deleted, all data associated with it will be lost and cannot be recovered. Always make sure to backup any important data before deleting a collection.
searchSearch for documents in a collection based on a query. This method accepts several parameters that can be used to filter, sort, and limit the results.
string - The search term, query, or keywordsnumber (optional) - Limit the number of search resultsRecord<string, unknown> (optional) - Weaviate filter object for advanced filtering. For more details, visit https://weaviate.io/developers/weaviate/api/graphql/filtersstring[] (optional) - An array of custom properties to include in the resultsnumber (optional) - Filters out passages that are further than this value from the question or context. Measured by cosine metric. Default is 0. Range accepted is 0 to 1const collectionId = 'a1b2c3d4-uuid';
const searchResults = await qna.search(collectionId, {
term: 'search term',
limit: 10,
where: {
operator: 'And',
operands: [
{
operator: 'GreaterThan',
path: ['publishDate'],
valueDate: '2020-01-01T00:00:00Z',
},
{
operator: 'LessThan',
path: ['publishDate'],
valueDate: '2022-01-01T00:00:00Z',
},
],
},
select: ['author', 'publishDate'],
});
// Example response
[
{
id: 'e5f6g7h8-uuid',
distance: '0.1234',
content: 'Found passage content',
sourceUrl: 'http://example.com/source-url',
loaderMetadata: {
custom: 'metadata'
},
document: {
id: 'i9j0k1l2-uuid',
name: 'Document Name'
}
}
]
In this example, the search method is called with advanced filtering and property selection options. The where parameter is used to filter the results based on the publishDate property, and the select parameter is used to include the author and publishDate properties of the selected passages in the response. As a result, the search returns a list of passages that meet the specified conditions and include the custom property values. Along with these properties, the result also includes new properties like sourceUrl, loaderMetadata and document.
askAsks a question and generates an answer based on the documents in a collection. This method accepts a set of parameters to configure the question-answering process and to fine-tune the generated outputs.
The ask method supports two modes: 'ask' and 'conversation'. Here are the details of each mode:
'ask' mode:
This mode allows you to ask a direct, standalone question. In this mode, the processing of the question and the generation of the answer are not influenced by any prior context or conversation history.
This mode is suitable for scenarios where a single question is to be answered independently, such as a search query or a factual question.
'conversation' mode:
This mode allows you to ask questions in the context of a conversation. This means that prior messages from the conversation will be taken into account while processing the question and generating the answer.
This mode is suitable for scenarios where a dialogue is happening, and the generation of an answer is dependent on the previous exchanges in the conversation. In this mode, you can supply previous conversation messages in the messages parameter, which accepts an array of message objects, each with a sender role ('assistant' or 'user') and the content of the message.
Both modes use a language model to generate an answer given a question and a collection of documents. How the prior messages are used to influence the retrieval of information and the generation of responses differs based on the mode used.
string - The question to askCompletionRequestMessage[] (optional) - An array of previous chat messages with roles 'user' and 'assistant'. Default is an empty arraynumber (optional) - Limit the number of search results. Default is 5.

collectionId: string - The ID of the collection to retrieve passages from.params: FindPassages (optional) - An object containing the following optional properties:
query: string (optional): Search query for filtering passages.from: number (optional): Pagination offset (the index of the first item on the page).size: number (optional): Maximum number of passages to retrieve (page size).mode: SearchMode (optional) - The search mode, either 'bm25' for full-text search or 'vector' for vector similarity search. Default is 'bm25'where: Record<string, unknown> (optional): A weaviate where filter. See Weaviate Filters for more information.Listing passages with pagination, query filter, and a specific search mode:
const collectionId = 'a1b2c3d4-uuid';
const params: FindPassages = {
query: 'sample query',
from: 0,
size: 10,
mode: 'vector',
};
const passages = await qna.listPassages(collectionId, params);
// Example response
{
items: [
{
id: 'x1y2z3w4-uuid',
content: 'This is the content of the passage.',
// ...other properties
},
// ...more passages
],
total: 123
}
This will return a list of passages from the specified collection that match the filter query and are ordered according to their vector similarity. It also supports a 'where' query for advanced filtering.
listPassagesInDocumentList all passages in a document with optional pagination, query, and ordering.
collectionId: string - The ID of the collection containing the document.
documentId: string - The ID of the document to retrieve passages from.
find: Find (optional) - Optional find parameters.
query: string (optional) - The search query to filter passages based on their content.mode: SearchMode (optional) - The search mode, either 'bm25' for full-text search or 'vector' for vector similarity search. Default is 'bm25'size: number (optional) - The number of passages to return per request. Defaults to 10.from: number (optional) - The starting index for fetching the passages, used for pagination.orderProperty: string (optional) - The property by which to order the passages, e.g., 'createdAt'.orderDirection: OrderDirection (optional) - The direction to order the passages, either 'asc' for ascending or 'desc' for descending.const collectionId = 'a1b2c3d4-uuid';
const documentId = 'e5f6g7h8-uuid';
const passages = await qna.listPassagesInDocument(collectionId, documentId, {
query: 'search query',
mode: 'bm25',
size: 10,

orderProperty: 'createdAt',
orderDirection: 'asc',
});

deletePassageDelete a passage from a collection by its ID. This method removes a specific passage from the given collection, based on the passage's ID.
string - The ID of the collection the passage belongs tostring - The ID of the passage to deleteIn this example, we provide the collectionId and passageId as input parameters to the deletePassage method. The specified passage will be deleted from the collection, with no direct response returned.
const collectionId = 'a1b2c3d4-uuid';
const passageId = 'x1y2z3w4-uuid';
await qna.deletePassage(collectionId, passageId);
// There's no direct response, the passage is deleted from the collection
Note: Deleting a passage is a permanent operation, and the removed data cannot be recovered. Be cautious when using this method and ensure you have backups of your data if necessary.
