Constructor Detail

DateFilterScoringSearcher

public DateFilterScoringSearcher(Directory directory)
                          throws IOException

Throws:

IOException

Method Detail

getFilteredCount

public int getFilteredCount()

Get the number of hits that was filtered (held in a ThreadLocal).

Specified by:

getFilteredCount in interface FilterCountingSearcher

Returns:

filtered results

resetFilteredCount

public void resetFilteredCount()

Reset the number of filtered hits.

Specified by:

resetFilteredCount in interface FilterCountingSearcher

search

public void search(Weight weight,
                   Filter filter,
                   HitCollector results)
            throws IOException

Copied the implementation of IndexSearcher.search(Weight weight, Filter filter, final HitCollector results) (Lucene 1.9.1) in order to add logic to increment filter count. The logical method to override is search(Query query, Filter filter), but the implementation of this does not allow us to slip in filter incrementation logic.

Specified by:

search in interface Searchable

Overrides:

search in class IndexSearcher

Parameters:

weight -

filter -

results -

Throws:

IOException

search

public TopDocs search(Query query,
                      Filter filter,
                      int nDocs)
               throws IOException

Deprecated. Deprecated in Lucene 1.9.1

modify scores of hits based on whether they conform to date range, and also perform boosting based on age of doc

Specified by:

search in interface Searchable

Overrides:

search in class Searcher

Throws:

IOException
