Examples of org.apache.lucene.queries.TermsFilter

org.apache.lucene.queries.TermsFilter
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)
