[MarkLogic Dev General] Behavior of cts:and-query() with 'ordered'option??

[Ian Small]

David -

"ordered" says that the subjects of the and clause need to occur in the
order specified.
So "ordered" of "cat", "dog" says that "cat" has to occur before "dog".
There is only one paragraph (the target of your search, per the first
parameter) that
matches this criteria, so only paragraph is returned.

Cheers
ian
