16:28
When estimating the number of rows visited by a range scan for which the keys consist of more than one field, consider prefixes of stat4 samples as well as the full samples. This generates more accurate estimates. (check-in: 3e0590de user: dan tags: trunk)
13:48
Use #ifdef to omit code that is only used for STAT3 and STAT4. (check-in: f2c9c5b5 user: drh tags: trunk)

11:50
Fix the bm25() function so that it multiplies scores by -1 before returning them. This means better matches have a lower numerical score, so "ORDER BY rank" (not "ORDER BY rank DESC") does what you want. (check-in: 3ee7b5a9 user: dan tags: fts5)
03:02
Remove some code that is commented out. (check-in: 55ff4291 user: drh tags: like-opt-fix)

16:45
The LIKE optimization must be applied twice, once for strings and a second time for BLOBs. Ticket [05f43be8fdda9f]. This check-in is a proof-of-concept of how that might be done. (check-in: 5757e803 user: drh tags: like-opt-fix)

13:43
Fix a typo in sqlite3ota.h. (check-in: 04087dec user: dan tags: ota-update)
