does anyone know why in a programmatically-run saved search, a filter criteria fetched from an existing saved search doesn't work? for context, I pulled out the filter for a Transaction-type Saved Search that returns Sales Invoices within a date range for a specific customer (

customermain.entityid

) using 

search.filterExpression

, yet when creating a saved search in SS2, adding that filter returns an error saying that it isn't a valid search criteria. here's the code snippet of the search I made. maybe I missed something?

var stateSearch = search.create({
			type: search.Type.TRANSACTION,
          	columns: [
              		{ name: 'ordertype' },
              		{ name: "mainline" },
              		{ name: "trandate" },
              		{ name: "tranid" },
              		{ name: "duedate" },
              		{ name: "amount" },
              		{ name: "type" }
            ],
		    filters: [{
              			name: "type",
						operator: "anyof",
						values: ["CustInvc"]
					 },
          			 {
              			name: "mainline",
						operator: "is",
						values: ['T']
					 },
          			 {
                        name: "customermain.entityid",
						operator: "is",
						values: ["Some Guy"]
					 },
          			 {
              			name: "trandate",
						operator: "within",
						values: [startDateField, todayDateField]
					 }]
		});

there are 2 types of ways to do filters

thanks @battk. changing the syntax of my filters based on what you linked did the trick for me. i did some more googling to figure out how to translate the format for date ranges, but this code worked for me.

filters: [
        		["type", search.Operator.ANYOF, "CustInvc"],
        		"and",
            	["mainline", <http://search.Operator.IS|search.Operator.IS>, "T"],
            	"and",
            	["customermain.entityid",  <http://search.Operator.IS|search.Operator.IS>, "Some Guy"],
            	"and",
            	["trandate",  search.Operator.ONORAFTER, startDateField],
            	"and",
            	["trandate",  search.Operator.BEFORE, todayDateField]
    	  ]

Thanks again.
