Is there a way to test SS 2.x Saved Searches with Advanced filters from the browser console?

Use require instead of define

@NSCoder, to expand on what @Timothy said. You can store the module in a variable in the console so you can use it without constantly using require. Sample:

//variables to hold module
var search;

//load module
require(['N/search'],function(s){
    //when loaded assign back to variable
    search = s;
    console.log("2.0 search module loaded");
});

You can then store this as a snippet in Dev Tools for easy access.

Thank You again..@jarens
