Search - Search Filters
Search filters (or refiners) are dynamic tools located on the left side, which can be used to drill down into a subset of your search results. You can filter by data source, document type, file format, date modified, languages, and more. The pane also displays the number of search results for each search filter.
These search filters are designed to be dynamic and will automatically adjust based on your search results. This ensures that you are only presented with filters relevant to the data in your current search query.
