Users – 

Does xindice provide an embedded facility to sort a RecordSet?   

For example, a command analogous to the SQL ORDER BY.

Just a thought; I think that dom4J has this functionality already.  When you
do a select nodes it has an alternative signature that takes a second XPath
that is used as the sorting criteria on the list that is returned and a
third signature that takes an additional boolean to trim the list to unique
entries. Seems that there should be some way to capitalize on this rather
than completely reinventing the wheel.

No you're right, but I think we're going to need to be the catalyst for it.
  We need XQuery far more then they do. We can worry about where the 
project lives once there is actually some code to worry about.

I've already spoken to Scott Boag about a shared XQuery implementation.  
They've got a little bit of waiting to do before they can move ahead 
with it though.

Not at all.

FWIW, I'm here to help. But I'm not *that* sure that an XQuery 
implementation should belong to XIndice: wouldn't it be better if such 
an implementation was done with, say, the Xalan team? I know they are 
deep into XSLT, but IIRC their data model is probably going to be the 
one that XIndice 2.0 will use, so I'd say that sharing efforts with them 
would be a Good Thing.

Am I wrong?

XPath has no direct facilities for sorting, so you need a higher level 
query language like XQuery to do that. For now you could pass the query 
result to an XSL-T stylesheet and use that to sort the nodes.

BTW, we could really use volunteers to work on an XQuery impl.
