I'd like to recommend standardization in the phone number field when submitting reviews to make searching by phone number more valuable. For example - say an AMP or provider has the number 333-444-5555. Some reviewers will enter "3334445555" in the phone field, while others will enter "333-444-5555" or "333.444.5555" or "(333) 444-5555" etc. If I now search for "3334445555", only reviews that match that format EXACTLY will come up. Even if I search by the last four digits 5555, only the reviews that have that on its own or preceded by a separator character (e.g. "-" or ".") will come up. Searching by phone number is often times the only way to pull up prior reviews of a given provider, especially if they a) have a name that is 3 letters or less, which is currently unsearchable, or b) are an agency without a name, e.g. the Hungarian shops in Brooklyn.
I think the easiest fix would be to strip all non-numeric characters from the phone field when reviews are submitted; alternatively, allowing sub-string matches in searches would at least allow looking up by the last 4 digits to work. Otherwise the site is great, keep up the good work!
