When searching for references (and especially when finding duplicates), reference titles (for example) may differ by a single character. E.g.
“This is a reference for Pieris brassicae” v
“This is a reference for Pieris-brassicae” v
“This is a reference for P. brassicae”
Ensuring that all of these are found is quite painful, since you need to set up 3 separate search fields. I’d much rather be able to type:
“This is a reference for P[ieris|.][|-]brassicae” or something similar.
