This should be implemented in an upper layer, not in the engine.

yes

yes, except of queries similar to "field LIKE '%something%'..."

yes, but you must implement the indexer.

this is not part of the engine, you would have to implement it.

this should be implemented in an upper layer (not in the kernel) IMHO

yes. currently, a student is also working on a metasearch module, so 
that the respective modules will be extended soon.

If you can give me a solid specification then it is not a problem to 
support all of them. ;)

You can always peek at Lucene library (Apache project). It could work 
for you to some degree, but it does not solve all your needs. Moreover, 
they tried to integrate a classic search (a la DBMS) with fulltext, but 
their solution is not as good as Oracle with InterMedia or Postgresql, 
at least, when you have plenty of data in DBMS module (AFAIK).
