Report filters provide the ability to limit the set of responses in the reports based on custom filter criteria. For example, if a survey contains a question asking users if they have a driver's license, a report filter could be created to only display the responses where the user answered "Yes" to this question.

There are three types of report filters: Date, Question, and User Attribute. Date filters limit the responses to only the dates within the specified range. Question filters limit the responses based on answers to questions in the survey. User attribute filters limit the responses based on attributes of the user who took the survey, such as company, location, name, custom data, or any other user field. 

Question filters vary depending on the type of question selected. Answers can be set to be equal to a response, contain a response, or, in the case of number and date questions, be greater than or less than a certain a value. 

One or more report filters may be applied to a survey. All of the filters are combined using "AND" logic, meaning that all filters must evaluate to "True" in order for a response to be included in the results. 

If a report has filters, the filters are applied to the overview report, the individual report, the text report, and the data export functionality. 

When working with a report with many questions, you may want to run multiple reports with various combinations of filters. Rather than deleting filters, you can set any filter to active or inactive on the page that displays the main list of report filters.
