Modifying the search mode
By default when searching entries on the View, GravityView will try to match any of the conditions requested in the search form.
This means if you have multiple search parameters ("Apple", "Orange"), by default GravityView will show entries with the words "Apple" OR "Orange" in them.
To modify this behaviour, in order to retrieve the entries that match all the search conditions ("Apple" AND "Orange"), download and install this plugin:
Download the plugin: GravityView Mod: Search Mode "All"
The search mode will be reset to all when using filter conditions powered by the Advanced Filter Extension.
