Doing an advanced search with specified date(s) returns all dates

[ldko]

Using the advanced search form, if you specify an exact date/timestamp or if you specify a start and/or end date, results for all dates of that URL are returned.

After creating this issue, I noticed it overlaps (or could be wholly the same problem (not sure)) #190.

This advanced search issue would be partially fixed by PR #225 , but it would only fix the case where you do an advanced search that includes both a start and end date. With #225 PR incorporated, exact date search or a search with only a start or an end date starts returning a 404 instead of all dates.

I haven't dug into the code at this point.
