Search does not work for MLS #

Front end site search does not work for MLS #
I tried searching for example A11275000 or #A11275000 or MLS #A11275000 none works.
It’s important to have. People often (almost all of them) when they call tell me MLS#
And I have to go to Miami MLS. Find it there. Copy address and by address find it on our site. (of course, I can see everything on MLS database, but I want to check how it looks on our site and also update some details on properties customer is inquiring about))
I think # is useless before MLS number on our site. Can you remove it?
You can make it like:
Property Features For MLS A11275000
Or it comes with # from API? And too difficult for you, or removing # can break the site?
