In the top right of one of your pages, in a subwindow, under the Search tab, I
typed "93744" (without quote marks).

What I expected was a list of pages referring to 93744, including the issue with
that number. What I got was "No matching search results found.", even when I
changed the Scope to "Entire openoffice.org domain".

I solved it by finding another page, where a Jump to Issue button was available.

I recommend either:
     -- Expand the ordinary search to return issues that match or refer to a
simple number typed into the search field, assuming the number has been assigned
to an issue, and order the results to put the issue assigned that number above
issues that merely refer secondarily to the number somewhere within it. The
search term might be alone or preceded by "Issue", "Issue #", "Issue No.", etc.
with variations in case and spacing. 
     -- Add a Jump to Issue button and entry field to the search results page
generated by any search. That's likelier easier to implement, but it means an
extra step for a search.

Thank you.
