Search form inserts spaces into keywords, rendering searches invalid. Under conditions I can't quite pin-down, the search feature on the public site will separate the last character of a keyword from the remainder of the word by a space, rendering the term meaningless. This appears to happen only when multiple keywords are supplied. For instance, try performing a search for "ibm suse". Note that the results reflect a search for "ib m sus e".
Looks like a bug in Text::Balanced, test case: perl -MText::Balanced -e '$s = ("ibm suse" =~ /^(.*)/)[0]; @words = Text::Balanced::extract_multiple($s); print join(",",@words)' ; outputs: ib,m sus,e ugh....
