ElasticQuery

ElasticQuery is an easy to use query builder for the rather verbose ElasticSearch DSL. It covers a large portion of the ES DSL, but does not currently have full coverage — pull requests welcome!

Installation

yarn

yarn add @shnhrrsn/elasticquery

npm

npm install --save @shnhrrsn/elasticquery

Documentation

TODO! In the mean time, check out some examples below, the tests and source code.

Examples

Create a Connection

const { ElasticSearch } = require('@shnhrrsn/elasticquery')
const search = new ElasticSearch({
  host: 'localhost:9200'
  index: 'locations'
})

Conditions

const results = await search.query('doc').where('country', 'US')

const results = await search.query('doc').whereNot('country', 'US')

const results = await search.query('doc').whereIn('country', [ 'US', 'CA' ])

const query = search.query('doc')
query.distance('location', '5mi', '40.782420', '-73.965600')
query.orDistance('location', '10mi', '40.782420', '-73.965600')

const query = search.query('doc')
query.range('established', '1700', '1800')

Aggregating

await search.query('doc').aggregate(agg => agg.terms('field'))

search.query('doc').aggregate(agg => {
  agg.terms('field', term => {
    term.aggregate(query => {
      query.sum('nested.sum1', sum => sum.as('sum1'))
      query.sum('sum2')
    })
  })
})

search.query('doc').aggregate(aggregate => {
  aggregate.filter(filter => {
    filter.where('abc', 123)
  })

  aggregate.dateHistogram('field', histogram => {
    histogram.interval('day')
    histogram.timezone('-05:00')
    histogram.bounds({ min: 'now-30d/d', max: 'now/d' })
    histogram.minDocCount(0)
    histogram.size(10)
  })
})
