Class GeoContextMapping

java.lang.Object

org.elasticsearch.search.suggest.completion.context.ContextMapping<GeoQueryContext>

org.elasticsearch.search.suggest.completion.context.GeoContextMapping

All Implemented Interfaces:

ToXContent

public class GeoContextMapping
extends ContextMapping<GeoQueryContext>

A ContextMapping that uses a geo location/area as a criteria. The suggestions can be boosted and/or filtered depending on whether it falls within an area, represented by a query geo hash with a specified precision GeoQueryContext defines the options for constructing a unit of query context for this context type

toInternalQueryContexts

public java.util.List<ContextMapping.InternalQueryContext> toInternalQueryContexts(java.util.List<GeoQueryContext> queryContexts)

Parse a list of GeoQueryContext using parser. A QueryContexts accepts one of the following forms:

• String: GeoQueryContext value with boost=1 precision=PRECISION neighbours=[PRECISION]
• Array:

  [GeoQueryContext, ..]

A GeoQueryContext has one of the following forms:

• Object:

  • GEO POINT

  • {"lat": <double>, "lon": <double>, "precision": <int>, "neighbours": <[int, ..]>}

  • {"context": <string>, "boost": <int>, "precision": <int>, "neighbours": <[int, ..]>}

  • {"context": <GEO POINT>, "boost": <int>, "precision": <int>, "neighbours": <[int, ..]>}

• String:

  GEO POINT
