Class TermsFilter
java.lang.Object
org.apache.lucene.search.Filter
org.apache.lucene.search.TermsFilter
- All Implemented Interfaces:
- Serializable
public class TermsFilter
- extends org.apache.lucene.search.Filter
Constructs a filter for docs matching any of the terms added to this class.
Unlike a RangeFilter this can be used for filtering on multiple terms that are not necessarily in
a sequence. An example might be a collection of primary keys from a database query result or perhaps
a choice of "category" labels picked by the end user. As a filter, this is much faster than the
equivalent query (a BooleanQuery with many "should" TermQueries)
