Suitescript nlapiSearchRecord cant load custom record - netsuite

Question

I've got what is probably a simple issue, but cant seem to find an answer to it.
I have a custom record, with an list field containing the item records in the account.
Whenever I run the script it returns the 2 rows in the custom record, rather than the specific record im trying to source.
I know its list is just the items list, but when i try '10' as the internal id of the specific item record it throws an error.
nlobjSearchFilter('custrecord_pm_int_inventory_item',null,'is','10');
it throws an error, i have seen similar posts on stackoverflow for this, but not exactly trying to load a custom record that has a list field of item
// if inventory item has been found, check to see if it exists in the item tracking record
var filt = [];
filt[0] = new nlobjSearchFilter('custrecord_tc_int_inventory_item',null,'is','88999 shipping');
var cols = [];
cols[0] = new nlobjSearchColumn('internalid');
cols[1] = new nlobjSearchColumn('custrecord_tc_int_inventory_item');
var search = nlapiSearchRecord('customrecord_tc_int_item_tracking',null,filt,cols);
Hopefully im just missing something simple, but i cant seem to load the record, any ideas greatly appreciated

Answer 1

You gotta use anyof operator and pass an array, here's how it should look:
// if inventory item has been found, check to see if it exists in the item tracking record
var filt = [];
filt[0] = new nlobjSearchFilter('custrecord_tc_int_inventory_item',null,'anyof',['10']);
var cols = [];
cols[0] = new nlobjSearchColumn('internalid');
cols[1] = new nlobjSearchColumn('custrecord_tc_int_inventory_item');
var search = nlapiSearchRecord('customrecord_tc_int_item_tracking',null,filt,cols);
