If the current result has only 1% records and less than 1000 records, sequential search is used even when index search is available. + You can disable this feature by ``GRN_TABLE_SELECT_ENOUGH_FILTERED_RATIO=0.0`` environment variable. + +* [load] improve error message. + Table name is included. + +* [load] add ``lock_table`` option. + If ``--lock_table yes`` is specified, ``load`` locks the target table while updating columns and applying ``--each``. + This option avoids "load" and "delete" conflicts but it'll reduce load performance. + +* [vector_find] avoid to crash with unsupported modes + +Fixes +^^^^^ + +* [index] fix a bug that offline index construction for text vector with ``HASH_KEY``. + It creates index with invalid section ID. + +* Fix a bug that ``--match_columns 'index[0] || index[9]'`` uses wrong section. + +* highlighter: fix a wrong highlight bug + It's caused when lexicon is hash table and keyword is less than N of N-gram. + +* [mruby] fix a bug that real error is hidden. + mruby doesn't support error propagation by no argument raise. + https://github.com/mruby/mruby/issues/290 + +* TokenNgram loose: fix a not found bug when query has only loose types. + ``highlight_html()`` with lexicon was also broken. + +* Fix a bug that text->number cast ignores trailing garbage. + "0garbage" should be cast error. + +* Fix an optimization bug for ``reference_column >= 'key_value'`` case + + .. _release-8-0-5: Release 8.0.5 - 2018-07-29 -------------- next part -------------- HTML����������������������������...
