Heinrich-- Thanks for replying! Actually, I gave a bad example. We will use PMID as the "key" and so won't need an index on that field. However, there are other examples of the same problem. To reduce the question to its simplest form, can I use Xpath in indexer patterns...?
A better example is last name of authors. There is one area of the document where LastName is a tag in the AuthorList/Author hierarchy. But there are also other places LastName appears. I would want to only index those within AuthorList/Author so I can find documents authored by a certain person. Does that make more sense? dan ----------------------- Dan, If I understand you right, you using PMID as unique key for your documents. If you retrieve your documents using your unique PMID you don't need any index, do you? Am I still on your track?
