Description copied from class: IndexPredicate

This method matches documents without calling an index subsystem. For primitive fields (e.g. integer, long) , the matching logic is consistent across this method and all known index implementations. For text fields (i.e. prefix and full-text) the semantics vary between this implementation and known index implementations:

Prefix: Lucene as well as IndexPredicate.match(Object) matches terms as true prefixes (prefix:foo -> `foo bar` matches, but `baz foo bar` does not match). The index implementation at Google tokenizes both the query and the indexed text and matches tokens individually (prefix:fo ba -> `baz foo bar` matches). Full text: Lucene uses a PhraseQuery to search for terms in full text fields in-order. The index implementation at Google as well as IndexPredicate.match(Object) tokenizes both the query and the indexed text and matches tokens individually.

Specified by:

match in interface Matchable<ChangeData>

Overrides:

match in class IndexPredicate<ChangeData>

Returns:

true if the predicate matches the provided I.
