AO keyword filter query exclude not working

[patphongs]

Summary

When using the query exclude functionality, the user types - in front of the term they want to exclude. For example: -committee

Those excludes need to go into a separate query parameter called q_exclude. Regular query statements go into the query parameter q.

We have a python function called parse_query that will parse the exclude params for the more keyword options box, but need something similar for the AO JS API fetch calls.

Example correct API call:
https://api.open.fec.gov/v1/legal/search?ao_doc_category_id=F&type=advisory_opinions&hits_returned=20&from_hit=0&q=nevada&q_exclude=committee&api_key=DEMO_KEY

Example incorrect API call:
https://fec-dev-api.app.cloud.gov/v1/legal/search/?api_key=&type=advisory_opinions&ao_citation_require_all=false&ao_doc_category_id=F&sort=-ao_no&q=nevada+-committee

Frequency

We just recently noticed this bug with AO search filters after we made the template upgrades

Notes, steps, considerations

• From the query string, look for the negation dash/hyphen, parse it into q_exclude

window.location like ?search_type=adrs&search=committee+-travel+-authorization

Fetch like ?type=adrs&hits_returned=20&from_hit=0&q=&q_exclude=travel+authorization

split on +- or %20-

(+-(travel+authorization) shouldn't be an issue)

How to Reproduce

1. Go to the AO search
2. In the Search keywords text box, type nevada -committee. This is doing a search for the word nevada and excluding the term committee. The query is sent without pushing committee into a separate query param q_exclude.

What if a user tries term1 -(term2 term3) or term1 -"word1 word2"?
