Hi Britt,
this is not really a bug, but a free text search. The search field is used to do a string search on several fields and the search string 124001-12-01-01 is interpreted as follows:
search for strings that contain the words 124001, 12 and 01 (given two times).
This can also lead to results like 124001-12-01-41, as all three words are contained in this string. You might try to use a = sign at the beginning of the search string. This leads to an exact search as far as I can see.
So input =124001-12-01-0 searches for projects which contain the expression 124001-12-01-01.
Best regards, Reinhard
