Methods

Modifier and Type	Method and Description
SpatialContext	boostedTo(float boost) Boost the query to a given value Most of the time positive float: - lower than 1 to diminish the weight - higher than 1 to increase the weight Could be negative but not unless you understand what is going on (advanced)
SpatialContext	filteredBy(org.apache.lucene.search.Filter filter) Filter the query results with the Filter instance
SpatialMatchingContext	onCoordinates(String field) An entity can have multiple Spatial annotations defining different sets of coordinates.
SpatialMatchingContext	onDefaultCoordinates() Used to create Spatial Queries on the default coordinates of an entity.
SpatialContext	withConstantScore() All results matching the query have a constant score equals to the boost FIXME is that true?

Method Detail

onCoordinates

public SpatialMatchingContext onCoordinates(String field)

Description copied from interface: SpatialContext

An entity can have multiple Spatial annotations defining different sets of coordinates. Each non-default Spatial instance has a name to identify it, use this method to pick one of these non-default coordinate fields.

Specified by:

onCoordinates in interface SpatialContext

Parameters:

field - The name of the set of coordinates to target for the query

Returns:

SpatialMatchingContext instance for continuation

onDefaultCoordinates

public SpatialMatchingContext onDefaultCoordinates()

Description copied from interface: SpatialContext

Used to create Spatial Queries on the default coordinates of an entity. This is the one to use when Spatial is being used without defining a custom value for Spatial.name().

Specified by:

onDefaultCoordinates in interface SpatialContext

Returns:

SpatialMatchingContext instance for continuation

boostedTo

public SpatialContext boostedTo(float boost)

Description copied from interface: QueryCustomization

Boost the query to a given value Most of the time positive float: - lower than 1 to diminish the weight - higher than 1 to increase the weight Could be negative but not unless you understand what is going on (advanced)

Specified by:

boostedTo in interface QueryCustomization<SpatialContext>

withConstantScore

public SpatialContext withConstantScore()

Description copied from interface: QueryCustomization

All results matching the query have a constant score equals to the boost FIXME is that true?

Specified by:

withConstantScore in interface QueryCustomization<SpatialContext>

filteredBy

public SpatialContext filteredBy(org.apache.lucene.search.Filter filter)

Description copied from interface: QueryCustomization

Filter the query results with the Filter instance

Specified by:

filteredBy in interface QueryCustomization<SpatialContext>
