In a word - no :-).

However, if you want to get more experience with learning how to query  
this stuff, I'd say have a look at the Lucene documentation and learn  
how to use those queries well. I say this because at the end, all you  
need to do is create a Lucene query and use that to create a  
CacheQuery instance. The complexity here is creating the Lucene query.  
The better you know Lucene, the better you can query the Cache :-).

Again, I think the easy thing here is to learn how to use Lucene  
queries well. Then you know what type of object you have in your Cache  
and will know how to get what you're looking for quite efficiently.
