XML Query Engine v0.89 is now available. This is a major update that
fixes a number of outstanding bugs and adds several new features and
optimizations. These include:

  o logical subquery operators 'and' and 'or'
  o set operators 'union' and 'intersect'
  o namespace support
  o setDoFullText(boolean) api for turning off element text indexing
    (speeds up indexing, query retrieval, and drastically reduces 
    index size in appropriate cases)
  o showDocTree(docID) api for quick visualization of element hierarchy
  o simple compound-word matching in element content
  o attribute content moved into index for improved speed and precision
  o a number of other optimizations, primarily to improve performance
    and reduce memory footprint during full-text queries

This version is getting very close to beta territory, since all major
features, with the exception of a persisted store, are now in place. The
download is available at:

I'm interested in feedback and particularly in bug reports as I get
closer to release. Any comments would be quite welcome.
