Mroonga 5.12 has been released!

Mroonga is a MySQL storage engine that supports fast fulltext search and geolocation search. It is CJK ready. It uses Groonga as a storage and fulltext search engine.

Mroonga 5.12 has been released!


Here are changes in this release. All of them are bug fixes:

  • Fixed a bug that search result may be 0 when you use range search by index
    • It's prone to cause when many records in the table are updated or deleted.
  • Fixed a bug that UDF such as mroonga_escape may return wrong result when JOIN is also used.

If your use case fits one of them, we recommend you to upgrade Mroonga.


See Release 5.12 - 2016-01-29 about detailed changes since 5.11.
