Survey - Point of Beginning

The advanced search option lets you select from any field within the survey based on the results in the database.

The AND/OR option allows you to run a search where all fields must meet your criteria (AND) or where one of the fields out of all the fields you select has to meet your criteria (OR). (i.e. where field1=yes AND field2=yes vs where field1=yes OR field2=yes)

The keyword search allows you to find keywords you are looking for within the survey notes.

Feel free to select from one or more drop-downs for a powerful, combined search to get the results you desire. Click the Run Advanced Search button when you are ready to perform your search.
