Exact Match for search query like: 17.1106

Hi, I am currently trying to make it so when you search for a specific attribute it will only return its exact match., in this case manufacturerPartNo, which is formatted differently for various manufacturer.

For example, when I search for: 17.1106, I get a lot of hits in the search:

I just want it to return the first result, as when someone searches for a manufacturer part number, it is always an exact search.

How can I achieve this?
