#15 Bad start position in viewdoc for the pubmed collection.

[Nicolas Buhours]

When I try to view a document that is in the pubmed collection (although the TGEN04 collection seems fine), the beginning of the abstract is truncated, whereas it is not in the summary on the result page.
It is probably because it gives a bad value to the start_pos_in_file metaIndex property.
Contrarily to the TGEN04 collection, this one has a lot of files. Maybe it is related...
