Custom Payload Analyzer and Query

Anonymous Wrote:

I'm working on providing advanced searching for annotated Medical
Documents (using UIMA). In the context of an annotated document, I
identify relevant medical terms, as well as the negation of certain terms.
Following what I've read and seen in Lucene examples, I've been able to
provide a search that takes into account the metadata contained in the
payload. Although very primitive, I've implemented a search which returns
the payloads (using PayloadSpanUtil), and then excludes those terms where
the payload doesn't meet the criteria.

Is the use of payloads I've described appropriate? Can I exclude/filter
the matching terms based on the payload within a query itself ? Are
there any examples that do this?
