Hi Melissa,
In order to search for businesses or facilities with Community Analyst or for that matter BAO, you need to directly use the term such as ‘Restaurants’ and it will pull the list of all the restaurants in the USA. If you are just looking for restaurants in California you can add geography of California and then limit the number of restaurants within the California boundary.
The limitation for the number of search results is 5000 and hence you might have to break down the geography (California) into counties to pull all the Restaurants in California.
The trial version comes with all the functionalities that the application offers. It’s just that you get 200 credits to work with and once that is consumed you won’t be able to access the application.
I hope this helps!
