Default Client API Search Behavior Change on Port 8000
The defined default search behavior for the Java, Node.js, and REST Client APIs is unfiltered search unless you override the default with your own options. Prior to MarkLogic 9, this default behavior was not honored when you used the Client APIs to interact with MarkLogic through the pre-defined App Server on port 8000.
As of MarkLogic 9, searches via the Client APIs on port 8000 default to unfiltered search. To get the old behavior, use query options that explicitly specify filtered search.
