Suggest values for company and location filters

Resolves free-text input to canonical company-filter values; two characters minimum. field=company returns company names with their domain when known — send name to nameLike, or domain to domains; add orgType=investor to search investors instead, whose domain is the value the investors filter takes. field=location returns fully qualified place names ("Dallas, Texas, United States") which are exactly what the headquartersCity filter takes — the qualification is what lets the geocoder tell six same-named cities apart, so send the whole string. Note that officeLocationsV2 is a different filter and takes country apiCodes from GET /companies/filter-options, not these place names. Same vocabulary as the product's type-ahead; free.
