Plural words problem

Hello, the classifieds page I am creating is for the Spanish language. The problem is that when I type "remeras" (t-shirts) in the search and press enter, it does not give me any results, even if there are ads with the word "remera". Is there a solution for this problem with plurals?

It's probably question related to mysql search. I do not think there is great solution, ideal is to just get rid of last 1-2 letters.

Ok, can you tell me what I should modify?

In search model (mode/Search.php), where you can find addPattern and remove last chars before adding pattern to class

In this way, if I search for "tshirts", internally it searches for matches like "tshir**" (in case of removing the last 2 characters), but the user is shown that their search was "tshits"?

@Alej
I recommend you to check what Mysql options you have as that's the engine for Osclass.
For your question, removal should only happen in back when creating condition for mysql.
