`CALL AUTOCOMPLETE()` sometimes produces a `List<Map<String, String>>`, sometimes `List<Map<String, Int>>` in JSON results

[Ocramius]

Bug Description:

Given following SQL query:

CALL AUTOCOMPLETE('hello', 'my_index', 1 as append);

When using the /sql endpoint, Manticore will respond with data such as [{"query": "hello"}, {"query": "helloer"}]

When using a numeric value, things change:

CALL AUTOCOMPLETE('123', 'my_index', 1 as append);

When using the /sql endpoint, Manticore will respond with data such as [{"query": 123}, {"query": 12345}]

It seems like some auto-magic casting is occurring? Is that intentional?

Manticore Search Version:

Thanks for the issue @Ocramius . I don't think the casting is intentional.
