> Lucas is a UIMA CAS consumer component which writes CAS data into a Lucene index. It is based on a XML-based "mapping configuration  file" in which the user can determine which UIMA annotations should be put into which Lucene field, and how this field is set up (e.g. indexed and/or stored). In addition, some basic functionality for (ontolgical) hypernym indexing is provided.
> Additionally, Lucas is able to perform offset-based token stream alignment and merging of UIMA annotations (via token position increment) in the same Lucene field (e.g. "documenttext" or "title")
