## Class ContainsPrefixTreeQuery

- java.lang.Object
- - org.apache.lucene.search.Query
  - - org.apache.lucene.spatial.prefix.AbstractPrefixTreeQuery
    - - org.apache.lucene.spatial.prefix.ContainsPrefixTreeQuery

-     public class ContainsPrefixTreeQuery
      extends AbstractPrefixTreeQuery

  Finds docs where its indexed shape `CONTAINS` the query shape. For use on `RecursivePrefixTreeStrategy`.
  WARNING: This API is experimental and might change in incompatible ways in the next release.

    Fields
    Modifier and Type | Field and 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.
