Elasticsearch query syntax

[jasny]

In addition to the query parameter, also support a q parameter. This uses the Elasticsearch uri query syntax.

The query should be converted to a MongoDB filter. Do not query to Elasticsearch.

• ?q=tag:foo
• ?q=user.id:12345
• ?q=date:[2018-01-01 TO 2018-12-31]

Queries will not do a full text search, so status:active doesn't mean status contains active, but status is active.
