Saved queries and filters are expressions kept in Coveo Enterprise Search's (CES) memory in order to be searched quickly. Note that it is impossible to apply a saved query or filter in the Advanced Search page.
Note: Saved queries and filters are optional, they can be removed in the Interface Editor (for more information, refer to Interface Editor Help > How to Modify Features).
To apply a saved query or filter in the Search page, expand the Select Saved Filter drop-down list and select the appropriate query or filter expression.
Note that, when only queries are saved, the Select Saved Filter drop-down list is named Select Saved Query.
