How to , in search results get exact term for the product?

Example; have products

...

If fill search filed with the "Sony cam 25" term, I will get, in search results, all sony products, not only "Sony cam 25"
I try to enater "Sony cam 25" with the quotation marks but nothing is changed?
Thank you
