WIP test: add drilldowns[LABEL].columns[NAME].stage test case without cache

[kenhys]

When the value of --drilldowns[LABEL].columns[NAME].stage parameter is
changed, Groonga returns result without using cache.

[kenhys]

I've expected that output of this case is different, but not. any idea?

[kou]

Could you try --drilldowns[LABEL].filter instead of --query?

Could you try --drilldowns[LABEL].filter instead of --query?

Could you explain what you mean precisely? @kou
In other test case, we discussed that --filter is not worked expectedly for stage, so switched to use --query.
In this case, I think that the situation is same as before. But is --drilldowns[LABEL].filter effective?

[kou]

Issue number please.

[kenhys]

In other test case

I means #678 as other test case.

[kou]

It's a --columns[NAME] test. This is a --drilldowns[LABEL].columns[NAME] test.

[kenhys]

Note that filtered stage is not supported yet. so this test always fails.
And the following part is meaningless because query is already processed before drilldown.

--match_columns items \
+  --output_columns content \
+  --query "Book"

See http://groonga.org/ja/docs/reference/commands/select.html#select-columns-name-stage about processing order of dynamic columns and drilldowns.
