How do I change the search key length? I'm using Search API and Fuzzysearch in D7, and it's unable to search for three letter words. Unfortunately, we have a TON of 3-letter acronyms at work, so these need to be searchable. I've looked in the Search API and Fuzzysearch settings, but can't see where to change the length of the search keys. 

I get the following error message when searching:


  The following search keys are too short or too common and were
  therefore ignored: "api".
go to admin/config/search/settings and change the length of Minimum word length to index to 2 and re-index the site.
