* WIP adding custom analyzer so we can do substring search efficiently
* Adding unit tests for title search
* formatting
* adds more title search unit tests
* organize helpers
* fixes issue caused by having two title mappings
* Removes camelcase token filter since it prevents you from searching for a substring of chars and numbers. Adds regression test.
* adds back mapping for title_phrase
* use simple analyzer for input query string so it doesn't filter out english stop words
* ran bleve tests, table snapshots updated
* ignore linter for "unused" test functions. They are very helpful for troubleshooting search. Keeping them.
* only log total hits and query cost if result not nil
* fixes failing test - one more field because there are two title mappings now
* fix test
* fixes test - only take first item when its the title
* Adds separate internal field for title ngram mapping.
When searching with a query, results are sorted by score desc.
When searching without a query, results are sorted by title desc.
Adjusts ngram max to be 10.
Text queries are a disjunction of an exact match, phrase match, and a match. Boosted to have priority in that order.
Adds more unit tests for searching.
* linter
* fix test
* ran tests - generated new test dash json
* sort by title phrase instead of title
* fix test - not relying on /apis/dashboard/search to apply title sorting anymore
wire up the ui to the new search api
