Changes to fts3auto.test to test OR, AND and NOT operations. check-in: e4ab6cdb10 user: dan tags: fts3-prefix-search
12:19
Use only unsigned values in the implementatin of LIKE and GLOB so that values won't overflow to negative when dealing with malformed UTF8. check-in: 77f01578bb user: drh tags: trunk
09:11
Fix a bug exposed by combining matchinfo(), NEAR and "ORDER BY rowid DESC". check-in: 5f6b87f420 user: dan tags: fts3-prefix-search
2011-06-09
10:48
Fix problems to do with using both OR and NEAR operators in a single expression. check-in: 4e8dd19eef user: dan tags: fts3-prefix-search
2011-06-08
18:39
Fix various issues to do with deferred tokens, NEAR expressions and matchinfo(). check-in: 3972a787df user: dan tags: fts3-prefix-search
2011-06-07
18:35
Have NEAR queries use incremental merging. Fix issues surrounding the deferred token optimization. check-in: 9d10a6846b user: dan tags: fts3-prefix-search
2011-06-06
18:14
Merge the latest trunk changes into the fts3-prefix-search branch. check-in: 567dd84359 user: drh tags: fts3-prefix-search
14:51
Modify fts3rnd.test to run tests for both "ORDER BY docid ASC" and "ORDER BY docid DESC" with both order=ASC and order=DESC FTS tables. Fixes for some bugs found. check-in: 89f2f482e0 user: dan tags: fts3-prefix-search
13:38
Add assert() statements to verify that u16 pointers associated with the enhancement in [897f56a158] are always 2-byte aligned. check-in: 98ccfa930e user: drh tags: trunk
06:55
Clean up the code for processing FTS4 options a bit. check-in: 0425138a23 user: dan tags: fts3-prefix-search
2011-06-04
20:13
Remove some unreachable code. check-in: 650e1a79ed user: dan tags: fts3-prefix-search
20:04
Allow the "order=DESC" and "order=ASC" parameters in FTS4 "CREATE VIRTUAL TABLE" statements. Tables created with "order=DESC" store all doclists in descending order, which allows optimizations normally applied to "ORDER BY docid ASC" queries to be used with "ORDER BY docid DESC" queries instead. check-in: f6a0193f5a user: dan tags: fts3-prefix-search
2011-06-03
18:00
FTS changes: Remove unreachable code. Fix bugs. When processing a large doclist incrementally, read from disk incrementally too. check-in: a4c7e28208 user: dan tags: fts3-prefix-search
2011-06-02
19:57
Changes to improve performance and support LIMIT clauses on fts3 tables. This branch is unstable for now. check-in: 28149a7882 user: dan tags: fts3-prefix-search
2011-05-28
15:57
Minor changes made while planning a larger change. check-in: 84097a4c75 user: dan tags: fts3-prefix-search
2011-05-25
19:17
If a prefix index of size N is not present, use a prefix index of size N+1 along with the terms index for queries for prefixes of length N. check-in: cc83991caa user: dan tags: fts3-prefix-search
18:47
Merge trunk changes into experimental fts3-prefix-search branch. check-in: f0f0a03db2 user: dan tags: fts3-prefix-search
18:46
Fix a case where a malloc() error could lead to mismatched virtual-table xBegin/xCommit/xRollback callbacks. check-in: d807304a69 user: dan tags: trunk
18:34
Change fts4 so that the prefix= parameter is passes a comma-separated list of integers. For each integer N, a separate index of all prefixes of length N bytes is created. check-in: be59bf4940 user: dan tags: fts3-prefix-search
2011-05-24
18:49
If the fts4 option prefix=1 is specified, have the fts4 module maintain an index of prefixes as well as terms. check-in: b5bdc63989 user: dan tags: fts3-prefix-search
15:36
Do not invoke the xRollbackTo or xRelease methods of a virtual table without having first invoked an appropriate xSavepoint method. Add assert() statements to FTS3/4 to verify that this is happening in all cases. check-in: 651ef24249 user: drh tags: trunk
