Search Function - settings and results

Hi,

I am currently trying to figure out the ‘search’ element / function.
I couldn’t find a good tutorial or thread on the whole topic or those single questions.

What I already did is set up a search and a template for ‘search results’, that works so far.

What I try to find out atm is:

  1. how to include ACF field content into the search (it seems to only include WP Posttitle and Posttext)
  2. is there a way to define the search requirements like ‘whole word’ / ‘part word’ / ‘at least 3 letters’ etc.
  3. what exactly does the setting “Query Bricks data in search results” (bricks/settings/general/miscellaneous) do
  4. how do I use the ‘additional parameters’ in content of the ‘search’ item

If you can help me out on one or more of these I’d appreciate it.

Philip
