Search results contain searched term as a string, but not as its own word!

Thanks, however, the problem is that I can only seem to apply one of those possible parameters/defaults in the array list in the link at a time. And I already need to use the one that filters ‘fields’.

I also need to know how to apply the 'words' => true parameter to the code shown in my controller (code above), which uses a slightly different code than shown in the search documentation examples. This is because I am calling the plugin that allows for “and” searches instead of just “or” searches when entering more than one word.

I tried adding to the “return array” part of my code, but it didn’t work:
return array(
‘query’ => $query,
‘results’ => $results,
‘words’ => true
);

Either way, with my controller code and with trying the method in the documentation examples, I would need to know how to call more than one “possible parameters/defaults”? Does anyone know how to make this happen? Thanks!!!
