I use Xindice 1 on Linux,
I have many XML documents, each contains 100 entry. I think some of these entries are repeated, is there any algorithm to be followed to avoid inserting repeated entries in the collection?
another question, if I inserted the document X.xml to the collection, can I add some entries to the same document in the collection later?
Thanks
