Search for a freq in database?

[kingzogofalbania]

Once youve downloaded the whole data base into your computer desktop program ... can you somehow search for a particular freq to see if it's in the database?
Thanks (again)

The database is in states counties and cities.
Look in the state.
Look in the county.
look in the city.
or look if it is statewide like state police.
