Re: How to specify document order location path for id

I think I've better articulated my question in the following example:
...
How do I perform the following queries?

1) What is the number of reports which are coded with either an "a" or "b" where the last "a" or "b" code of the report (in document order) is an "a"?

(correct number is 3. Yes, this has been double checked.)

2) What is the number of reports which are coded with either an "a" or "b" where the last "a" or "b" code of the report (in document order) is a "b".

(correct number is 1. Yes, this has been double-checked.)

Unfortunate that I couldn't apply them to my application because my example was too simplified.
