How to show Checkboxes with Fulltext Search Filter Exposed? I have created a simple search with three filter options of "Contains any of the word", "all of the words" and "none of the word", as shown in the figure below.

I used Search API, and later created a view out of it.

What am I missing that this is not allowing me to show Checkboxes :(. I will be very thankful for your help. I just need to convert them to checkboxes.
Currently BEF doesn't support tweaking the display of the filter operator, only the filter itself. But this would be a great addition -- feel free to post a feature request in the BEF issue queue.

Thanks.
