>                 URL: https://issues.apache.org/jira/browse/LUCENE-668
>             Project: Lucene - Java
>          Issue Type: Improvement
>          Components: core/search
>    Affects Versions: 1.9, 2.0.0, 2.1
>         Environment: All
>            Reporter: Fernando Mato Mira
>            Priority: Minor

> 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.
