public class DisjointSpatialFilter
- extends Filter
A Spatial Filter implementing SpatialOperation.IsDisjointTo
in terms
of a SpatialStrategy
's support for SpatialOperation.Intersects
.
A document is considered disjoint if it has spatial data that does not
intersect with the query shape. Another way of looking at this is that it's
a way to invert a query shape.
- WARNING: This API is experimental and might change in incompatible ways in the next release.
DisjointSpatialFilter
public DisjointSpatialFilter(SpatialStrategy strategy,
SpatialArgs args,
String field)
- Parameters:
strategy
- Needed to compute intersectsargs
- Used in spatial intersectionfield
- This field is used to determine which docs have spatial data via
FieldCache.getDocsWithField(org.apache.lucene.index.AtomicReader, String)
.
Passing null will assume all docs have spatial data.
