FF Master Search is an add-on Code Snippet that will allow you to search the content of any Formidable Form Entry directly from MySQL using the front end of your WordPress installation (the Google Search of Formidable Forms). The search term will be highlighted in RED and displayed in a grid format. The details of the entry can be viewed through a modal and exported as PDF if needed. This is a fantastic tool for developers or anyone running a Formidable Forms site with dozens of forms and entries that need to be searched without building dozens of views or search forms. You can also exclude entries from specified forms if required.
