Fields

Modifier and Type	Field	Description
protected boolean	multiOverlappingIndexedShapes	If the spatial data for a document is comprised of multiple overlapping or adjacent parts, it might fail to match a query shape when doing the CONTAINS predicate when the sum of those shapes contain the query shape but none do individually.

Field Detail

multiOverlappingIndexedShapes

protected final boolean multiOverlappingIndexedShapes

If the spatial data for a document is comprised of multiple overlapping or adjacent parts, it might fail to match a query shape when doing the CONTAINS predicate when the sum of those shapes contain the query shape but none do individually. Set this to false to increase performance if you don't care about that circumstance (such as if your indexed data doesn't even have such conditions). See LUCENE-5062.

ContainsPrefixTreeQuery

public ContainsPrefixTreeQuery(Shape queryShape,
                               String fieldName,
                               SpatialPrefixTree grid,

                               boolean multiOverlappingIndexedShapes)

Method Detail

equals

public boolean equals(Object o)

Description copied from class: Query

Override and implement query instance equivalence properly in a subclass. This is required so that QueryCache works properly. Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical that other instance. Utility methods are provided for certain repetitive code.

Overrides:

equals in class AbstractPrefixTreeQuery

See Also:

Query.sameClassAs(Object), Query.classHash()

hashCode

public int hashCode()

Description copied from class: Query

Override and implement query hash code properly in a subclass. This is required so that QueryCache works properly.

Overrides:

hashCode in class AbstractPrefixTreeQuery

See Also:

Query.equals(Object)

toString

public String toString(String field)

Description copied from class: Query

Prints a query to a string, with field assumed to be the default field and omitted.

Specified by:

toString in class Query

getDocIdSet

protected DocIdSet getDocIdSet(LeafReaderContext context)
                        throws IOException

Specified by:

getDocIdSet in class AbstractPrefixTreeQuery

Throws:

IOException
