Please document query syntax

[ribrdb]

Please document what syntax you can use for the q field. The api documentation mentions * and -.
From reading closed issues I assume phrases are supported using double quotes. I also see examples using field:value but I can't find any documentation for this. This information should all be documented in one place.

Thanks for the feedback: I'll document this in the next round of updates to the docs.

For now, you've pretty much covered all the supported syntax:

• wildcard *
• exclusion of words via -
• phrase match by wrapping the words in quotes

field:value syntax is only for filtering. To target the fields used for querying, use the query_by param.
