Have FTS take advantage of "docid<?" constraints when they are present. Extend the FTS "incremental doclist" optimization so that it is used for tokens within multi-token phrases. check-in: baf8ce59 user: dan tags: trunk

Merge latest trunk changes. Closed-Leaf check-in: 24aa20da user: dan tags: fts4-docid-range-constraints

Allow FTS4 multi-token phrases to use a combination of in-memory and incrementally loaded doclists. This allows phrases to (partially) benefit from incremental doclists without disabling the deferred token optimization. check-in: f6819c5f user: dan tags: fts4-docid-range-constraints

Allow multi-token phrases to load doclists from the database incrementally. This allows queries that feature such phrases to benefit from the "docid<?" optimization. check-in: ea543f08 user: dan tags: fts4-docid-range-constraints
