Re: [Exist-open] Status report: query optimization

[<jmf...@cn...>]

Very nice document! After reading it, I have a couple of questions about 
current SVN implementation:

*	Although it seems that, does the optimizer support other operators, like < 
or >=?
*	Are optimized expressions involving attributes? QName indexes do not 
distinguish among elements and attributes (I guess from my own experience).
*	And the last, is this expression being optimized?

for $entry in (#exist:optimize#) { 
collection('IntAct')//i:hostOrganism[@ncbiTaxId='3562'] }
         return
                 $entry

	Best Regards,
		José María
