Get list of inventory items from NetSuite - netsuite

Question

Is there a way to retrieve an array or list of specific inventory items in NetSuite with one call? I can not seem to find any documentation regarding this. I have gone through the SuiteTalk training course and it does not contain any information on retrieving a list of items without the internalID.
On page 73 of this document there is a function getInventoryItemList(itemKeysArray) that is called with an array of inventory item id's. However this function does not exist anywhere and I am assuming is a custom function but they never show the code for it.
The only two ways I can see doing this would be to pull every single inventory item out of NetSuite and import the internalID's into our local database, this seems like a lot of extra work to me. Another option I thought of is to loop over an array of the line items and perform an ItemSearchBasic for every element and get the internalID that way, this seems like a worse idea than just storing them in the local database. I am hoping someone can confirm and show me if there is a much easier way of doing what I need.

Here is a version of what I use when I need to get the a list of items (minus company specific data). I just removed our data, and set it build/return an array. This is in SuiteScript 2.0, just FYI.
require(['N/search','N/record'],function(search,record){
function buildItemArray(){
var itemArray=[];
searchItems();
itemArray=runSearch(itemArray);
deleteSearch();
log.debug(itemArray);
}
function searchItems(context){
var itemSearch=search.create({
type:search.Type.INVENTORY_ITEM,
title:'Inventory_Item_Search',
id:'customsearch_inventory_item_search',
columns:['internalid','itemid'],
filters:['isinactive','is','F']
});
itemSearch.save();
}
function runSearch(itemArray){
var mySearch=search.load({id:'customsearch_inventory_item_search'});
mySearch.run().each(function(result){
var item={};
item.itemID=result.getValue({name:'itemid'});
item.internalID=result.getValue({name:'internalid'});
itemArray.push(item);
return true;
});
return itemArray;
}
function deleteSearch(){
search.delete({id:'customsearch_inventory_item_search'});
}
buildItemArray();
});

There are a number of ways to do that but the idea of collecting the item ids from the line items is the one I normally use.
You can then use GetList to retrieve details about each item.
