"typographically-correct" punctuation (which is using a hyphen-minus, not sure if that's correct!) is entered by some users, but "direct database search" is unable to match text containing a hyphen-minus (U+002D) to text that contains a "typographically-correct" hyphen (U+2010).  The only workaround is to create a search alias, which many editors fail to consider, or remove in ignorance of why the alias was entered.

IMO, direct database search should accomodate users who type without extra software and match with results who users using extra software have edited.  The frequent errors that indexed search gives causes users to use direct database search, and the inability of direct database search to consider user-unfriendly punctuation either results in users failing to find a match, or creating a duplicate.
