Description:
This PR updates search behavior to use a word-based approach instead of a substring match. Doing so allows index-based searching which is a lot more performant (especially when searching through alert summaries).
Additionally, the alert query was broken up into two steps, one to get a list of services that match the query, and a second purely for the alerts with matching queries or service names. This substantially improved query time and memory use in Postgres.
