Improved the performance\*\* of job searches and company searches by \*\*up to 30x\*\* when using some of the following filters:

-   `company_name_partial_match_or`
-   `company_name_partial_match_not`
-   `company_location_pattern_or`
-   `company_description_pattern_or`
-   `company_description_pattern_not`
-   `job_title_pattern_or`
-   `job_title_pattern_not`
-   `job_location_pattern_not`
-   `job_description_pattern_not`

This will have effect especially when passing large arrays of values in them (of 50+ elements). Queries that before would take ~50 seconds are now taking 2-3 seconds, according to our tests.
