What do you want matched? Without the quotemeta it would match
"fileAtxt", this is not normally the behavior you desire. Basically
it all comes down to this: always use quotemeta unless the variable is
known to contain the string form of a regex. Also, it is a good idea
to note the end of the quotemeta like this
s/\Q${search}\E/replace/
