 prefuse.data.search.KeywordSearchTupleSet
| KeywordSearchTupleSet | | public class KeywordSearchTupleSet extends SearchTupleSet (Code) | |
SearchTupleSet implementation that performs text searches on indexed Tuple
data using the Lucene search engine.
Lucene is an open source search
engine supporting full text indexing and keyword search. Please refer to
the Lucene web page for more information. Note that for this class to be
used by prefuse applications, the Lucene classes must be included on the
application classpath.
