Change blocksearch.php engine to work like search for association in back office

[hakeryk2]

Hello community,

In my shop I have plenty of products with names like K-1, KL-0 etc and basic module blocksearch is using prestashop built-in engine which is using a plenty of variables like tags,attributes etc which is pretty much useless in my case. Lot of people is  using search bar to find specific product.

 

So this is my question:

How to change this mechanism to work in much more simple way, in example: like this in back office when You are search for product association in back office while adding a product. The association search engine works perfect every time and is search for complex strings as well without indexing, weight etc. 

 

Any idea?
