Equally divide the results of a saved search via SuiteScript

Use case: Customer has a scheduled script with multiple deployments running simultaneously on different queues. They need the results of the saved search to be equally divided across each script deployment.

The following code snippet illustrates how to equally divide the search results of a saved search between several deployments of a script that are executing at the same time:

//create a filter array
var filters   = new Array();

//set filter depending on the deployment instance that is executing
if(deployId == 'customdeploy_auto_item_fulfillment_asc'){
        filter[0] = new nlobjSearchFilter('formulanumeric',null,'equalto','0');
        filter[0].setFormula('MOD({internalid},4)');
}
else if (deployId == 'customdeploy_auto_item_fulfillment_desc'){
        filter[0] = new nlobjSearchFilter('formulanumeric',null,'equalto','1');
        filter[0].setFormula('MOD({internalid},4)');
}
else if (deployId == 'customdeploy_auto_item_fulfillment_q3'){
        filter[0] = new nlobjSearchFilter('formulanumeric',null,'equalto','2');
        filter[0].setFormula('MOD({internalid},4)');
}
else if (deployId == 'customdeploy_auto_item_fulfillment_q4'){
        filter[0] = new nlobjSearchFilter('formulanumeric',null,'equalto','3');
        filter[0].setFormula('MOD({internalid},4)');
}

//execute search
var searchresults = nlapiSearchRecord('salesorder', 1541 , filter, null);
