I think i suggested this a while back, so yes, i must agree that search lik=

this would make sense. This in fact turns tags into hyperlinks and the whol=
e=20
data set into a semantic web... And gives us a way to do relevance-based=20
keyword search on the debian archive. I also suggested using fuzzy tags to=
=20
further facilitate this (iow, add scores to the tag/package relations via=20
bayesian tagger or something like that and then use that score when scoring=
 a=20
match... this _may_ be a bit off, but it may be still worth trying... I don=
't=20
believe fully manual tagging of the archive is feasible or even sustainable=
).=20
And the bayes can use much more input data than it does today to get some=20
better precision out of it... It is not going to be perfect either way. But=

google is freaking far from perfect, but it is probably the single most=20
useful web search tool.
