A logical feature enhancement to improve search across CS Forms search fields and the native search element.
- show search suggestions as the user starts typing
- show alternative related search phrases based on what the user types
- show the last couple of searches the user performed (when logged in?)
- provide options to tailor the search engine to a specific post type, taxonomy, custom fields, PDF contents, and other factors. This would allow you to create any number of search engines for specific needs
- highlight exact search matches in search results
- allow to apply custom weights to the various search factors to tailor the results rankings
- Search stats and analytics to see what your visitors are searching for and whether they found the content they needed
Maybe some of these could be developed in a separate premium extension? CS Forms basically competes with FacetWP and other premium form plugins, and these search features would challenge search plugins like SearchWP.
