Side note: I just put a recipe on-line that shows how the very same
GoodRelations elements used for describing offers can be used for
describing demand with the gr:seeks property.
http://tr.im/grseeks
BTW, you can combine that with most other recipes from
http://tr.im/cookbook
For instance, you could attach an image of a car wreck using
foaf:depiction and ask for offers to repair (or to dispose ;-) ) that car.

Right, I agree this is the key bit of 'Part 2 of the solution'
(looser, Google-like results may also be desirable, but that would be
icing).
Part 1 is a little more than front end though, IMHO. You'd also need to :
* snag the searcher's profile
* generate filter clauses based on that
(in practice the filtering would probably be better the other way
around, i.e. reduce search space using profile facts for triple
matching, then use something like FILTER regex(?object, ?searchterms,
"i") )
Having said that a bit of experimentation is no doubt needed to get a
good interaction between the sloppy text bits and the explicit profile
stuff - e.g. if I searched for "airports" (and my profile contained my
geo location), behind the scenes you'd probably want "airports" to map
to ?s a x:Airport - something your Entity Search tool presumably can
do (alas it keeps timing out for me right now).
Cheers,
Danny.
