Hi Rahul, I have some other business at the moment, but perhaps I can look into this more deeply later on. Or perhaps someone else has time to run your scripts locally?
There is nothing wrong with the basic idea of sending some identifier as a request param. You will have to send some ID to be able to update it. So that is just fine. You could argue though that using the node-uri or base-uri is a potential security risk, in the sense that you are revealing database details that the outside world doesn't necessarily need to know. And people might send fake update requests, sending fake uris, when your scripts will be available world-wide, possibly corrupting all your data in the database, perhaps even data that is not related to this application, but just happens to reside in the same database. It would be safer to give each document a unique ID, using xdmp:random or so, and use that as identifier, and apply some collection or directory restrictions internally as well. But, perhaps keep that as a later concern and try to get your code to work first. About your second question: how to call a function in search-lib.xqy, import it and use the prefix you specify in the import line. Looks like you are doing it the right way.
