Add an "OR" Condition to a GlideRecord Query in ServiceNow

GlideRecordOr.js

var myLog = "";
	var gr = new GlideRecord("sys_user");
	//New object to build OR query
	var q1 = gr.addQuery("title", "CONTAINS", "VP");
	q1.addOrCondition("title", "CONTAINS", "Vice");
	q1.addOrCondition("title", "CONTAINS", "Chief");
	
	//"switch back" to the GR object
	gr.query();
	while (gr.next()) {
		myLog += gr.title + ", ";
	}
	
	gs.addInfoMessage("VPs : " + myLog);
	gs.log("***CM: " + myLog, "CM");

Note that there is also another way to add an OR query: you can use .addEcodedQuery() and then ^NQ to start a new query.
This is the same as writing (some query) OR (some other query).
