Uwe Schindler commented on LUCENE-1345:
---------------------------------------
Here some ideas how to implement search() with Query and Filter:
- User runs Searcher.search() using a Filter as the only parameter. As every
Filter is also a ConstantScoreQuery, the query can be executed and returns
score 1.0 for all matching documents.
- User runs Searcher.search() using a Query as the only parameter: No change,
all is the same as before
- User runs Searcher.search() using a BooleanQuery as parameter: If the
BooleanQuery does not contain a Query that is subclass of Filter (the new
Filter) everything as usual. If the BooleanQuery only contains exactly one
Filter and nothing else the Filter is used as a constant score query. If
BooleanQuery contains clauses with Queries and Filters the new algorithm could
be used: The queries are executed and the results filtered with the filters.
I hope this explains how I would implement the combined Filters and Queries.
