- Searchable: Determines whether a user’s search request can access this field. Filterable: Indicates that this field can be used as a filter. For example, if a user wishes to search for “high heels”, the field that contains these search terms must be marked as filterable. This lets Azure Search return only the rows in the index that contain “high heels” in that field. Facetable: Indicates whether a search request can return the number of items in the index with a specific characteristic, such as color=red. An application can also request the number of items within a specific range, such as all items whose price is between 100 and 200 euros. Sortable: Indicates that search results can be sorted by this field. Some fields, such as a string containing a paragraph of text, might not allow this, since sorting on a paragraph probably wouldn’t make much sense.
