I run a forum board and one of the main products in my industry is called B&R.

When any one tries to search for "B&R" in the search board of Invision Board, it comes up with nothing.

I've tried B and R.
I've tried quotes "B&R" etc

Is there any settings or anything I can do to make this search query work? I thought it was fixed in a previous version but now since upgrading, the problem came back for me. 

Any suggestions or help? Pointers I could try?

As its only 3 characters, its likely that causing you issues with finding, rather than the ampersand. mysql search, by default, has a minimum 4 letters for full text search. You would need to contact your hosting company if you wish to have this changed, as its a mysql setting.

This may help you if you are doing this yourself

Or even better, he can switch to Elasticsearch or Opensearch.
