I am having a hard time getting the right results, its still including the word minifig in the return and I am trying to filter that out:

select distinct  item_title, sold_price
from products
where product_type = 1
AND (item_title like '%2114%')
AND (item_title not like '%mini%figure%' or item_title not like '%minifig%')
AND (item_title LIKE '%chopov%')       
ORDER BY sold_price desc

This is the result I am getting back.  The word minifig is clearly still in there.  How can i do this query to work better?

Yes that worked much better, why does it need the AND and not work with the OR in the parenthesis?

Basically what you have in that line is two conditions:

1) Item-title should not contain 'mini%figure'
2) Item-title should not contain 'minifig'

with "or" you are saying that either one can evaluate to true for the whole line to evaluate to true.

So Item-title like: "Lego ninjago skeleton warrior chopov minifig 2259 2114" evaluates like:

1) true
2) false

problem is that with "or" your whole line is still true.
