Search system

I have a lot of products on my site,
Can i set the search script to find products which contains the strings i'm looking for? No matter the position?

Example
Xperia Xa Ultra
Searching for Xperia Ultra will not find the product

I have several cases like that, that's why i'm asking for help
I sell phone cases
simple searches as a3 case
will not find A3 Tpu Case or A3 Silicon Case, just because there are a string between A3 and Case
I believe it should be natural to appears all A3 Cases for this search, that is exactly what the users whats.. to show all A3 Cases, no matter what the material

Pleeeeease any help to improove this?
