There are many hidden gems in ServiceNow which are undocumented for some reason or the other. One such thing is a interesting function that I found while looking into the script include 'StdChangeUtilsSNC', called applyEncodedQuery() of GlideRecord.

Let's just say you have a use case where you have a encoded query and want to create or update a record using it. Here comes applyEncodedQuery() to your rescue. Below is a quick sample on how you can use the function.

var filter = 'caller_id=javascript:gs.getUserID()^active=true^short_description=Test^state=2';
var records = new GlideRecord('incident');
records.initialize();
records.applyEncodedQuery(filter);
records.insert();

The above code creates a incident with caller, short description and state being 'In Progress'.

Note: Tested the function in global scope.
