Incremental Search
------------------
Key: LUCENE-668
URL: http://issues.apache.org/jira/browse/LUCENE-668
Project: Lucene - Java
Issue Type: Improvement
Components: Search
Affects Versions: 2.0.0, 1.9, 2.0.1, 2.1
Environment: All
Reporter: Fernando Mato Mira
Add full support for long searches executed in steps.
QueryFilters only support narrowing down a set of results, they don't allow
extending it with OR clauses. They also don't allow to add new clauses to
SpanQueries.
This facility is needed because repeatedly creating new queries and executing a
full, more complicated query at each step is not efficient for search sessions
where you may have chains of hundreds of such steps.
