org.springmodules.lucene.search.core.HitExtractor

Callback interface for extracting datas from hits of search result.

Used for output search results in the LuceneSearchTemplate. Alternatively, the Lucene HitCollector class can be used directly. @author Thierry Templier @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(Query,HitExtractor) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(Query,HitExtractor,Filter) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(Query,HitExtractor,Filter,Sort) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(Query,HitExtractor,Sort) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(QueryCreator,HitExtractor) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(QueryCreator,HitExtractor,Filter) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(QueryCreator,HitExtractor,Filter,Sort) @see org.springmodules.lucene.search.core.LuceneSearchTemplate#search(QueryCreator,HitExtractor,Sort)
