How do you use query.filters.FulllName._contains on the Directory Model

Question

GOAL

If you want to query and filter FullNames from the Directory Model, how do you do it? Can filters.FullName._contains = be used?

What I've Tried

I've tried this in the Directory Model's Server Script. This returns all the GSuite records, cool.

var gQ = app.models.GSuite.newQuery();
gQ.filters.FullName._contains = '';  // filter empty string
var recs = gQ.run();
return recs; // returns all records

When I change the filter string to a character, I get no records.

var gQ = app.models.GSuite.newQuery();
gQ.filters.FullName._contains = 'a';  // filter the letter a
var recs = gQ.run();
return recs; // returns - recs undefined 

Question

What is wrong with the string I assign to filters.FullName._contains =?

What am I doing wrong?

Case Sensitive Solution

This script filters the Directory Model using a Custom Parameter, but it does not use filters.FullName._contains =.

Instead, using Javascript's search(), each FullName get's a RegEx evaluation. if (rec.FullName.search(eFilter) > -1))

Server Script for Directory Model

var gQ = app.models.GSuite.newQuery();
var gD = gQ.run();

if (query.parameters.FilteredGSuiteEmail === null) {
  return gD; // return all records
}

var eFilter = query.parameters.FilteredGSuiteEmail;
console.info("eFilter: " + eFilter);

var recs = [];
gD.forEach(function(rec) {
  console.log("searchValue: " + rec.FullName.search(eFilter));
  //console.log("search: " + rec.FullName);
  if(rec.FullName.search(eFilter) > -1) {
    console.log("search: " + rec.FullName);
    var newRec = app.models.GSuite.newRecord();
    newRec.FullName = rec.FullName;
    newRec.PrimaryEmail = rec.PrimaryEmail;
    recs.push(newRec);    
  }
});
return recs;

I need to convert my filter string to a RegEx argument that is case-insensitive.

Is there a better way to do this?
