Class BitsetFilterCache

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, org.apache.lucene.index.IndexReader.ClosedListener, RemovalListener<org.apache.lucene.index.IndexReader.CacheKey,​Cache<org.apache.lucene.search.Query,​BitsetFilterCache.Value>>, IndexComponent

    public final class BitsetFilterCache
    extends AbstractIndexComponent
    implements org.apache.lucene.index.IndexReader.ClosedListener, RemovalListener<org.apache.lucene.index.IndexReader.CacheKey,​Cache<org.apache.lucene.search.Query,​BitsetFilterCache.Value>>, java.io.Closeable
    This is a cache for BitDocIdSet based filters and is unbounded by size or time.

    Use this cache with care, only components that require that a filter is to be materialized as a BitDocIdSet and require that it should always be around should use this cache, otherwise the QueryCache should be used instead.
