I am quite new to Lucene, but I have searched the FAQs and consulted the mailinglist archive. I debugged through the source codes as well.
I have writen an Analyzer, that analyzes a stream by sending it to a whole pipeline of linguistic processing and uses the internal representation to construct a TokenStream, that tokenizes chunks (semantic units). The Term-Attribute String hold the abstract representations of those units. For further uses (for instance: highlighting the results in text), I need access to the OffsetAttribute, that I defined in my TokenStream implementation. Like in StandardTokenizer I defined an OffsetAttribute to save the left and right values of the original chunks. Now I want to search for all documents containing an "AdjectivePhrase", get those APs from the Documents and highlight all APs in the found documents. I tried to find results by getting TermPositions with "Reader.termPositions(term)" and then iterate over the positions, but the positions only represent the left offset. Is there another function to get structured results from term queries over documents, where I can get the whole set of attributes, that I constructed in the TokenStream with addAttribute(Class)? I did not find such a function, but I guess I dont know all retrieval methods of Lucene, yet. For my search I used the IndexSearcher.
