I tried searching "a state of" without the commas and realized MB is not searching for complete words, i think adding it as an option would give more precise results.
An example is searching for "win" with the commas. You can find winner in the results.
If you search for " win " will only find tracks where win is not at the beginning and not at the end.
If you simply search for win without commas, will get winding, window, etc
