It's a fine line to add "easy" query object factory methods:
  - this single term query is often not enough
  - even when it is, are you doing a TermQuery, a FuzzyTermQuery  
(which fuzzy factor), a PrefixQuery or even why not a RangeQuery?

where are you going to draw the line? I would rather see some DSL to  
build Lucene queries which I would like to work on for HSearch as soon  
as free time comes by.
