solr-node

Simple Solr Node Client Project

Install

npm install solr-node

Usage

• Client: http://godong9.github.io/solr-node/docs/Client.html
• Query: http://godong9.github.io/solr-node/docs/Query.html

Create Client

// Require module
var SolrNode = require('solr-node');

// Create client
var client = new SolrNode({
    host: '127.0.0.1',
    port: '8983',
    core: 'test',
    protocol: 'http'
});

// Set logger level (can be set to DEBUG, INFO, WARN, ERROR, FATAL or OFF)
require('log4js').getLogger('solr-node').level = 'DEBUG';

Search

Search can be executed with a simple text query or an object query.

Text

Text queries are similar to what one would find on the SOLR Core UI, EX:

From the URL: http://localhost:8080/solr/products/select?q=*%3A*&wt=json

The Query would be:

*:*&wt=json

NOTE: url decoded ':' from %3A.

Object

Object based queries can be simple or complex using chaining. Each method of the Query object returns an instance of itself.

Examples:

Simple:

client.query().q({text:'test', title:'test'});

Complex and chained:

client.query()
    .q({text:'test', title:'test'})
    .addParams({
        wt: 'json',
        indent: true
    })
    .start(1)
    .rows(1)
;

Query Examples

// Create query
var strQuery = client.query().q('text:test');
var objQuery = client.query().q({text:'test', title:'test'});
var myStrQuery = 'q=text:test&wt=json';

// Search documents using strQuery
solrClient.search(strQuery, function (err, result) {
   if (err) {
      console.log(err);
      return;
   }
   console.log('Response:', result.response);
});

// Search documents using objQuery
solrClient.search(objQuery, function (err, result) {
   if (err) {
      console.log(err);
      return;
   }
   console.log('Response:', result.response);
});

// Search documents using myStrQuery
solrClient.search(myStrQuery, function (err, result) {
   if (err) {
      console.log(err);
      return;
   }
   console.log('Response:', result.response);
});

Update

// JSON Data
var data = {
    text: 'test',
    title: 'test'
};

// Update document to Solr server
client.update(data, function(err, result) {
   if (err) {
      console.log(err);
      return;
   }
   console.log('Response:', result.responseHeader);
});

Delete

// Delete Query
var strQuery = 'id:testid'
var objQuery = {id:'testid'}

// Delete document using strQuery
client.delete(strQuery, function(err, result) {
   if (err) {
      console.log(err);
      return;
   }
   console.log('Response:', result.responseHeader);
});

// Delete document using objQuery
client.delete(objQuery, function(err, result) {
   if (err) {
      console.log(err);
      return;
   }
   console.log('Response:', result.responseHeader);
});

Promise support

Skip the callback to get a promise back. ie:

var result = solrClient.search(query)
    .then(function(result) {
      console.log('Response:', result.response);
    })
    .catch(function(err) {
      console.error(err);
    });

You can also use async/await:

try {
   const result = await solrClient.search(query);
   console.log('Response:', result.response);
} catch(e) {
   console.error(err);
}
