I'm trying to implement this and should be able to contribute any succesful results, but I need to produce context on a per-field basis. Eg. if I got a token hit in the text body of a document, but the first hit token was a word in the section title, I'd want to generate context around the token in the text body. I had been using a TokenStream to try this. However, lucene's Token class doesn't seem to have any concept of fields, (even when I tokenStream() a document that is in the index with a whole bunch of fields). Is there any reason for this? Moreover, any suggestions of how to find the information I need? The natural thing seems to be to have a field-aware token stream, but I'm not sure how I'd go about implementing that...
