The example of `array<object>` style is: + `[{"key1": weight1}, {"key2": weight2}]`. + +* Supported to search `!(XXX OPERATOR VALUE)` by index. Supported + operator is not only `>` but also `>=`, `<`, `<=`, `==` and `!=`. + +* Supported index search for "!(column == CONSTANT)". The example in + this case is: `!(column == 29)` and so on. + +* Supported more "!" optimization in the following patterns. + + * `!(column @ "X") && (column @ "Y")` + * `(column @ "Y") && !(column @ "X")` + * `(column @ "Y") &! !(column @ "X")` + +* Supported to search `XXX || !(column @ "xxx")` by index. + +* [:doc:`/reference/commands/dump`] Changed to use `'{"x": 1, "y": + 2}'` style for not referenced weight vector. This change doesn't + affect to old Groonga because it already supports one. + +* [experimental] Supported `GRN_ORDER_BY_ESTIMATED_SIZE_ENABLE` + environment variable. This variable controls whether query + optimization which is based on estimated size is applied or not. + This feature is disabled by default. Set + `GRN_ORDER_BY_ESTIMATED_SIZE_ENABLE=yes` if you want to try it. + +* [:doc:`/reference/commands/select`] Added query log for `columns`, + `drilldown` evaluation. + +* [:doc:`/reference/commands/select`] Changed query log format for + `drilldown`. This is backward incompatible change, but it only + affects users who convert query log by own programs. + +* [:doc:`/reference/commands/table_remove`] Reduced temporary memory + usage. It's enabled when the number of max threads is 0. + +* [:doc:`/reference/commands/select`] `columns[LABEL](N)` is used for + query log format instead of `columns(N)[LABEL]`.. + +* [:doc:`/tutorial/query_expansion`] Updated example to use vector + column because it is recommended way. [Reported by Gurunavi, Inc] + +* Supported to detect canceled request while locking. It fixes the + problem that `request_cancel` is ignored unexpectedly while locking. + +* [:doc:`/reference/commands/logical_select`] Supported `initial` and + `filtered` stage dynamic columns. The examples are: + `--columns[LABEL].stage initial` or `--columns[LABEL].stage + filtered`. + +* [:doc:`/reference/commands/logical_select`] Supported + `match_columns`, `query` and `drilldown_filter` option. + +* [:doc:`/reference/function/highlight_html`] Supported similar search. + +* [:doc:`/reference/commands/logical_select`] Supported `initial` and + stage dynamic columns in labeled drilldown. The examples is: + `--drilldowns[LABEL].stage initial`. + +* [:doc:`/reference/commands/logical_select`] Supported window + function in dynamic column. + +* [:doc:`/reference/commands/select`] Added documentation about + dynamic columns. + +* [:doc:`/reference/window_function`] Added section about window + functions. + +* [:doc:`/install/centos`] Dropped CentOS 5 support because of EOL. + +* [httpd] Updated bundled nginx to 1.11.12 + +* Supported to disable AND match optimization by environment variable. + You can disable this feature by + `GRN_TABLE_SELECT_AND_MIN_SKIP_ENABLE=no`. This feature is enable by + default. + +* [:doc:`/reference/functions/vector_new`] Added a new function to + create a new vector. + +* [:doc:`/reference/commands/select`] Added documentation about + `drilldown_filter`. + +Fixes +^^^^^ + +* [:doc:`/reference/commands/lock_clear`] Fixed a crash bug against + temporary database. + +* Fixed a problem that dynamically updated index size was increased + for natural language since Grooonga 6.1.4. + +* [:doc:`/reference/commands/select`] Fixed a bug that "A && B.C @ X" + may not return records that should be matched. + +* Fixed a conflict with `grn_io_flush()` and + `grn_io_expire()`. Without this change, if `io_flush` and `load` + command are executed simultaneously in specific timing, it causes a + crash bug by access violation. + +* [:doc:`/reference/commands/logical_table_remove`] Fixed a crash bug + when the max number of threads is 1. + +Thanks +^^^^^^ + +* Gurunavi, Inc. + .. _release-7-0-0: Release 7.0.0 - 2017-02-09 -------------- next part -------------- HTML����������������������������...Download
