]

select Values  \
  --filter 'numbers == [2, 3, 4]'  \
  --output_columns 'numbers'
[[0,0.0,0.0],[[[1],[["numbers","Int32"]],[[2,3,4]]]]]

grndb Added support new option `--since`

We can specify a scope of an inspection.

We can specify the modified time as ISO 8601 format or -NUNIT format such as -3days or -2.5weeks format.

Here is an example that specifies –since option in ISO 8601 format:

% grmdb check --since=2019-06-24T18:16:22 /var/lib/groonga/db/db

In above example, the objects which are modified after 2019-06-24T18:16:22 are checked.

Here is an example that specifies –since option in -NUNIT format:

% grmdb check --since=-7d /var/lib/groonga/db/db

In above example, the objects which are modified in recent 7 days are checked.

Please also refer to grndb#since.

query Added `default_operator`.

We can customize operator when "keyword1 keyword2". "keyword1 Keyword2" is AND operation in default.

We can change "keyword1 keyword2"'s operator except AND as below.

        ],
        [
          "name",
