Searching for the book title "Why be happy when you could be normal?" (without quotes) returns the following error "'ERMS_ComputeRelevance08' failed because parameter 23 is not allowed to be null." in the catalog search results.

However, other catalog systems and discovery searches such as Vega (https://mdpls.na.iiivega.com), Sirsi (https://jkpl.ent.sirsi.net/system), and Koha (https://catalog.mylakelibrary.org) accommodate this search with results, without having to remove the "?" or surround string with quotes, which most patrons wouldn't know to do (we had library staff that didn't even do this by default).

This seems like a pretty basic glitch to fix in the system by default rather than trying to force patrons (and staff) to learn and perform advanced searching techniques for a book title, especially when other systems make an accommodation for this, but the only option at this time is to propose this as an enhancement idea.
