Ok, thanks. I understand offset will come with a performance slowdown, but should be ok for my purpose.
However, how can I get the offset(s) as part of the rank function implementation? The FTS offsets function is private: SQLITE_PRIVATE void sqlite3Fts3Offsets(sqlite3_context*, Fts3Cursor*); Regards Ben Am 14.05.13 14:06 schrieb "Richard Hipp" unter <d...@sqlite.org>: >On Mon, May 13, 2013 at 12:25 PM, Stadin, Benjamin < >benjamin.sta...@heidelberg-mobil.com> wrote: > >> Hi all, >> >> I need to implement a ranking that considers the search result's token >> distance (so either the actual character offset, or token offset from >>the >> beginning of the text).
