In the search function i have the option that visitors can search on a field that is a Multiple Checkbox. But if a user has choosed 2 checkboxes (for example, Green and Red) and than i go search on a user that has Green, i cant find this user. If i search by Green and Red than that user is find. But what i'd like is that you can find that user if you have choose only Green in the search function to.
This is old, but in case anyone stumbles upon this looking for an answer: Have you tried editing the search criteria parameters in the backend? Log in to Joomla Admin > Components > Community Builder > List Management. From there scroll to the bottom of the page and find the box that says "List parameters" and change the Multi-Search Criteria as needed. save. Viola.
