I use the search button here extensively, and have found a trick that you can try. Try inserting an asterisk after strings that are shorter than 3 characters.

For example, if you search for "V8", it finds no matches. However, if you search for "V8*", you get a long list of matches. This is because the search engine understands that the "*" is a wildcard.

This might not work or apply to what you are needing it for, but it has been somewhat helpful to me.
