How to avoid search result limit exceeding error in NetSuite saved search

NetSuite has a limit of 4000 results at a time for every saved search result execution (run function). If the search result returns more than 4000 results this can lead to a search limit exceeding the error.
The error message will be: ‘SSS_SEARCH_FOR_EACH_LIMIT_EXCEEDED’:

This error can be avoided by using a paging function for running the search. The ‘page size’ option can be used to limit the number of results in a ‘searchObj.run()’ function
Use the following function for executing the search object:

/*****************************************************************************************
 //To iterate over and initiate format of each saved search result
 *****************************************************************************************/
const iterateSavedSearch = (searchObj) => {
    var response = [];
    var searchPageRanges;
    try {
        searchPageRanges = searchObj.runPaged({
            pageSize: 1000
        });
    } catch (err) {
        return [];
    }
    if (searchPageRanges.pageRanges.length < 1)
        return [];

    var pageRangeLength = searchPageRanges.pageRanges.length;
    log.debug('pageRangeLength', pageRangeLength);

    for (var pageIndex = 0; pageIndex < pageRangeLength; pageIndex++)
        searchPageRanges.fetch({
            index: pageIndex
        }).data.forEach(function(result) {
            response.push(result);
        });

    return response;
}
