5988572876 If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing.

5db2605a80 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.

9211f8a6ce 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.
