This module provides functions to create secondary index (SI) filter predicates for use in query operations via the Client#query command.

Example

const Aerospike = require('aerospike')
const Context = Aerospike.cdt.Context

Aerospike.connect().then(async (client) => {
  // find any records that have a recent location within 1000m radius of the specified coordinates
  let geoFilter = Aerospike.filter.geoWithinRadius('recent', 103.8, 1.305, 1000, Aerospike.indexType.LIST, new Context().addListIndex(0))
  let query = client.query('test', 'demo')
  query.where(geoFilter)

  let results = await query.results()
  for (let record in results) {
    console.log(record.bins.recent)
  }
  client.close()
})

Classes

SindexFilterPredicate

Methods

(static) contains(bin, value, indexType, context) → {module:aerospike/filter~SindexFilterPredicate}

Filter for list/map membership.

Description:

  • The filter matches records with a bin that has a list or map value that contain the given string or integer.

Source:
Since:
  • v2.0
Parameters:
Name Type Description
bin string

The name of the bin.
value string | number

The value that should be a member of the list or map in the bin.
indexType number

One of module:aerospike.indexType, i.e. LIST, MAPVALUES or MAPKEYS.
context Object

The CdtContext of the index.
Returns:

SI filter predicate, that can be applied to queries using Query#where.

Type
module:aerospike/filter~SindexFilterPredicate

(static) equal(bin, value) → {module:aerospike/filter~SindexFilterPredicate}

String/integer equality filter.

Description:

  • The filter matches records with a bin that matches a specified string or integer value.

Source:
Parameters:
Name Type Description
bin string

The name of the bin.
value string

The filter value.
Returns:

SI filter predicate, that can be applied to queries using Query#where.
