How it treats punctuation is indeed configurable, you can index data in multiple ways to allow the choice to be made at search time. It can also be contextually aware to distinguish for instance end-of-sentence dots from domain name or math expression dots. Matching "foocompany.com" from "company.com" can be achieved with a wildcard or fuzzy search. If you specify an exact match then that's what you get.
