Get relevant results first MySQL/PHP?

OK, so I have decided to make a little search where you can find what words you can find in a string with random placed characters. An example on the query I use is:

"SELECT * FROM 'words' WHERE 'word' LIKE '%a%', 'word' LIKE '%v%', 'word' LIKE '%c%', 'word' LIKE '%b%';"(Mine is just dynamic)

In the DB I have a column witch contains the word "abc" and I want it to show up first. So basically I want the results witch is the most relevant on the top and wondered if this was possible within the query. Or do I have to get the whole database then sort it out in PHP.

I have about +3000 results and it shows with that query every single with those characters witch is many. Can I put a "LIMIT 0, 20" on the query if I want the relevancy?

Hope someone can help me out here :-) If you dint understand a part tell me and I will explain more. Or you need more info.
