Is wildcard search bad UX?

I have never heard of a wild card search until recently. I cannot find anything that says whether this is bad UX or good UX. My team just says it's outdated, unfortunately I need facts if we are not going to use it. I feel like we should just give the users the capability to search like you normally would with the option to select a checkbox that says "Exact Matches."

Can anyone point me to facts, websites etc. that show why we shouldn't use wildcard character or shed some light on this topic?

Currently these are the facts I have:

• Wild card character is used by developers, but we should not expect this for our end users. We want to make it as easy as possible for them
• Outdated (this isn't a strong point because it can be argued against)
