Search doesn't naturally show results for a specific category

For some reason on a music site I'm working on the search shows electric keyboards instead of drums if I type in drums.

 

Drums is a subcategory of percussions. Electric keyboards is a subcategory of pianos.

 

 

The site is in French and drums is "batterie" in that language but regardless, I had to use the "band-aid" approach and use Preferences/Search/alias "batterie"=> "percussions" for anything even remotely similar to show up.

 

Any ideas ?

 

Also I get this : "'products' => $search['result'], // DEPRECATED (since to 1.4), not use this: conflict with block_cart module" is there something I need to use to replace this ?
