Delicious does Keyword Search

About sodding time too. The number of times I've had to look through hundreds of results looking for links I saw but lost one way or another is just stupid.

Couldn't get it to logically work - weird & not very relevant results in English (I was looking for a page from MY bookmarks, not a very large DB).
Other languages (searched for tagged words) - turned an Hash error (looks like a [non-western] service crash),
don't you love it?

System error
error: Can't use an undefined value as a HASH reference at /www/del.icio.us/site/search/index line 110.
