Changes

Here are important changes in this release:

Improvements

  • load Added support for ISO 8601 time format.

    load support the following format by this modification.

    • YYYY-MM-ddThh:mm:ss.sZ
    • YYYY-MM-ddThh:mm:ss.s+10:00
    • YYYY-MM-ddThh:mm:ss.s-10:00

    We can also use t and z characters instead of T and Z in this syntax. We can also use / character instead of - in this syntax. However, note that this is not an ISO 8601 format. This format is present for compatibility.

  • select Added a new query_flags DISABLE_PREFIX_SEARCH.

    We can use the prefix search operators ^ and * as search keywords by DISABLE_PREFIX_SEARCH as below.

    This feature is useful if we want to search documents including ^ and *.

      table_create Users TABLE_PAT_KEY ShortText

  load --table Users
  [
  {"_key": "alice"},
  {"_key": "alan"},
  {"_key": "ba*"}
  ]

  select Users \
    --match_columns "_key" \
    --query "a*" \
    --query_flags "DISABLE_PREFIX_SEARCH"
  [[0,0.0,0.0],[[[1],[["_id","UInt32"],["_key","ShortText"]],[3,"ba*"]]]]

      table_create Users TABLE_PAT_KEY ShortText

  load --table Users
  [
  {"_key": "alice"},
  {"_key": "alan"},
  {"_key": "^a"}
  ]

  select Users \
    --query "_key:^a" \
    --query_flags "ALLOW_COLUMN|DISABLE_PREFIX_SEARCH"
  [[0,0.0,0.0],[[[1],[["_id","UInt32"],["_key","ShortText"]],[3,"^a"]]]]

  • select Added a new query_flags DISABLE_AND_NOT.

    We can use AND NOT operators - as search keywords by DISABLE_AND_NOT as below.

    This feature is useful if we want to search documents including -.

      table_create Users TABLE_PAT_KEY ShortText

  load --table Users
  [
  {"_key": "alice"},
  {"_key": "bob"},
  {"_key": "cab-"}
  ]

  select Users   --match_columns "_key"   --query "b - a"   --query_flags "DISABLE_AND_NOT"
  [[0,0.0,0.0],[[[1],[["_id","UInt32"],["_key","ShortText"]],[3,"cab-"]]]]

Fixes

  • [The browser based administration tool] Fixed a bug that a search query that is inputted to non-administration mode is sent even if we input checks to the checkbox for the administration mode of a record list.

Known Issues

  • Currently, Groonga has a bug that there is possible that data is corrupt when we execute many additions, delete, and update data to vector column.

  • *< and *> only valid when we use query() the right side of filter condition. If we specify as below, *< and *> work as &&.

    • 'content @ "Groonga" *< content @ "Mroonga"'

  • Groonga may not return records that should match caused by GRN_II_CURSOR_SET_MIN_ENABLE.
