Usage

Orama is quite simple to use. The first thing to do is to create a new database instance and set an indexing schema:

import { create, insert, remove, search } from '@orama/orama'

const db = await create({
  schema: {
    author: 'string',
    quote: 'string',
  },
})

If you are using Node.js without ESM, please see build section below on how to properly require Orama.

Orama will only index string properties, but will allow you to set and store additional data if needed.

Once the db instance is created, you can start adding some documents:

await insert(db, {
  quote: 'It is during our darkest moments that we must focus to see the light.',
  author: 'Aristotle',
})

await insert(db, {
  quote: 'If you really look closely, most overnight successes took a long time.',
  author: 'Steve Jobs',
})

await insert(db, {
  quote: 'If you are not willing to risk the usual, you will have to settle for the ordinary.',
  author: 'Jim Rohn',
})

await insert(db, {
  quote: "You miss 100% of the shots you don't take",
  author: 'Wayne Gretzky - Michael Scott',
})

After the data has been inserted, you can finally start to query the database.

const searchResult = await search(db, {
  term: 'if',
  properties: '*',
  boost: {
    author: 1.5, // optional: boost author field by x1.5
  },
})

In the case above, you will be searching for all the documents containing the word if, looking up in every schema property (AKA index):

{
  elapsed: {
    raw: 184541,
    formatted: '184μs',
  },
  hits: [
    {
      id: '41013877-56',
      score: 0.025085832971998432,
      document: {
        quote: 'If you really look closely, most overnight successes took a long time.',
        author: 'Steve Jobs'
      }
    },
    {
      id: '41013877-107',
      score: 0.02315615351261394,
      document: {
        quote: 'If you are not willing to risk the usual, you will have to settle for the ordinary.',
        author: 'Jim Rohn'
      }
    }
  ],
  count: 2
}

You can also restrict the lookup to a specific property:

const searchResult = await search(db, {
  term: 'Michael',
  properties: ['author'],
})

Result:

{
  elapsed: {
    raw: 172166,
    formatted: '172μs',
  },
  hits: [
    {
      id: '41045799-144',
      score: 0.12041199826559248,
      document: {
        quote: "You miss 100% of the shots you don't take",
        author: 'Wayne Gretzky - Michael Scott'
      }
    }
  ],
  count: 1
}

If needed, you can also delete a given document by using the remove method:

await remove(db, '41045799-144')

Using with CommonJS

Orama is packaged as ES modules, suitable for Node.js, Deno, Bun and modern browsers.

In most cases, simply import or @orama/orama will suffice ✨.

In Node.js, when not using ESM (with "type": "module" in the package.json), you have several ways to properly require Orama. Starting with version 0.4.0 it becomes:

async function main() {
  const { create, insert } = await import('@orama/orama')

  const db = create(/* ... */)
  insert(db, {
    /* ... */
  })
}

main().catch(console.error)

Use CJS requires

Orama methods can be required as CommonJS modules by requiring from @orama/orama.

const { create, insert } = require("@orama/orama")

create(/* ... */)
  .then(db => insert(db, { /* ... */ })
  .catch(console.error)

Language

Orama supports multiple languages. By default, it will use the english language,

You can specify a different language by using the defaultLanguage property during Orama initialization.

By default, Orama will analyze your input using an English Porter Stemmer function.
You can replace the default stemmer with a custom one, or a pre-built one shipped with the default Orama installation.

Example:

import { create } from '@orama/orama'
import { stemmer } from '@orama/orama/stemmers/it'

const db = await create({
  schema: {
    author: 'string',
    quote: 'string',
  },
  language: 'italian',
  components: {
    tokenizer: {
      stemmingFn: stemmer,
    },
  },
})

Example using CJS (see using with commonJS above):

async function main() {
  const { create } = await import('@orama/orama')
  const { stemmer } = await import('@orama/orama/stemmers/it')

  const db = await create({
    schema: {
      author: 'string',
      quote: 'string',
    },
    language: 'italian',
    components: {
      tokenizer: {
        stemmingFn: stemmer,
      },
    },
  })
}

main()

Right now, Orama supports 26 languages and stemmers out of the box:
