Hi!

Just a newbie question. I apologise if it has been answered earlier.
Is it possible to add indexes for the metadata attributes of the documents?
I've been trying to do this, but the query optimizer doesn't seem to use the
index. I'm trying to make a temporal (timerelated) database. Each document
will be valid for a given period of time, and this information is stored as
two metadata attributes, start and stop, for each document. I'm then running
a query to check for documents valid at time T. This query would look like
this in XPath: "//*//@time:start<='T' and //*//@time:stop>'T' ". (time is
the prefix for the two attributes).
I have added an index for the start attribute with the following call to
addIndex:
addIndex("http://erik.com", "start", "node-attribute-equality-number");
Where "http://erik.com" is the namespace used when setting the metadata. A
similar index has been set for stop.
So the question is, if it is possible to index metadata, what am I doing
wrong?

Thanks in advance
Regards,
Erik Bråten

say T and you'll be OK.
