No surprise really that the TokenStream cannot be re-accessed. I just had no clue what else to try ...
>Since you are storing the term vector, you could retrieve that using >IndexReader.getTermFreqVector. > OK, didn't see that coming, but glad it did -- I have tried that, and indeed I can get the TermFreqVector for the Field in which I am interested, and it contains the same sort of data as were once in the TokenStream, all fine. Now I notice (from googling) that I can also downcast TermFreqVector to TermPositionVector, which contains the offsets (which I will need). So -- under what conditions would that cast fail? thanks, Paul --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
