That's not very much, as far as large databases go. Xindice should be able to 
handle such number of documents fine.

However you did not say what is the mean/average/max size of each document. 
Since you are talking about "dozens of values" I'm guessing documents are rather 
small.

Current version of Xindice does not support XQuery. Currently you can use only 
XPath and XUpdate with Xindice.

I'd guess almost any XML DB should handle such volume Ok.
