Hi Todd, I load 10000 small xml documents(without defaultnamespace) in my xindice1.1b4 the smaple doc is as:
<?xml version="1.0"?> <entry id="10000"> <name>Charaka Laws</name> <address>694 Westhead Lane, San Jose</address> <phone>05896697157</phone> </entry> and added index by xindice command line tool such as: xindice ai -c xmldb:xindice://localhost:18080/db/littleblackbook -n address -p address I did the query as: xindice xpath -c xmldb:xindice://localhost:8080/db/littleblackbook -q "/entry/address[text()='595 Anjomshoaa Avenue, San Jose']" the speed gained with index than without index(that means my previous exception caugth in my log file can be ignored?). with my xml doc contains defaultnamespace i can not issue the command as: xindice ai -c xmldb:xindice://localhost:18080/db3/ildg/cssm/mdc/configurations -n crcCheckSum -p [http://www.lqcd.org/ildg/QCDml/ensemble1.1]crcCheckSum xindice: No match. if I used command like: xindice ai -c xmldb:xindice://localhost:8080/db/demo/ensembles -n crcCheckSum -p crcCheckSum it will create index, but querying seems no gain on speed such as: xindice xapth -c xmldb:xindice://localhost:18080/db3/ildg/cssm/mdc/configurations -s "br=http://www.lqcd.org/ildg/QCDml/config1.1"; -q "/br:gaugeConfiguration/br:management/br:crcCheckSum[text()='82f0c85d3a9d922cd95e634f1c9539cc']" So, what might be the problems?
