Roy, Quick example. Index A has fields 'title' and 'contents'. Field 'contents' is stored in A as Field.UnStored. This means that you cannot retrieve the original content of the 'contents' field, since that value was not stored verbatim in the index. Therefore, you cannot create a new Document instance, pull out String value of the 'contents' field from A, use it to create another field, add it to the new Document instance, and add that Document to a new index B using addDocument method.
addIndexes method does not need to pull out the original String field values from Documents, so it will work. Otis --- [EMAIL PROTECTED] wrote: > Otis, > > Thanks for the reply.
