Interface QueryTransformer
- All Known Implementing Classes:
- AbstractTermExpander, MultiIndexTermExpander
public interface QueryTransformer
A strategy for transforming queries.
Instances of this class represent query transformation that are applied at the
structural level—that is, when the query has already been parsed and turned
into a composite Query object.
If your only need it to replace terms, for instance, for query expansion, you
can subclass from AbstractTermExpander, which just requires specifying how
to expand a term or a prefix.
