Paul,
It is possible to reconstruct a document from the index, but it is a
potentially lossy proposition, since stemming and other manglings
might have gone on. Look at Luke and see how it does it (you can
"reconstruct and edit" a document from its UI).

hi,
My mission is currently to update an index by marking adding a flag
field on some documents.
For this, I seem to have the only following possibility:
- search for the documents in question, store them, filter them
- modify the documents in accordance
- delete the modified documents
- put back the documents
However, I seem to experiment and fear that unstored-fields will be
lost underway... I, of course, do not wish to re-run the analysis
process here (which is complex because of the xml-nature on the back).
Will these fields indeed be lost ?
Is there no way to "copy the token-streams" (as it's anyways stored
in the index in some way) ?
thanks
paul
