Circulars: Implement query_string method with fallback

[tylerbarna]

Description

This changes the search method to query_string rather than simple_query_string. The former addresses all of the use cases outlined in #2288, but there is the drawback of it not being as tolerant to incorrect syntax as the latter. As a result, I implemented a fallback where opensearch switches to multi_match if the query is invalid for query_string.

Note: this is still behind the CIRCULARS_LUCENE feature flag

Testing

1. Navigate to the circulars archive
2. Submit a standard search for something like LIGO. This should return the results as expected.
3. Submit a lucene search for something like subject:LIGO AND subject:Swift . The only results should include circulars with both "LIGO" and "Swift" in the subject.
4. Submit a lucene search for something like submitter:LIGO. This should only return a couple of circulars where the submitter has their LIGO association included.
5. Submit a lucene search for something like submitter:LIGO AND. Rather than failing due to the incorrect lucene syntax, it should fall back onto the multi_match method and show results different from the previous test.
