Sharepoint online - search/rest api -filter results in URL

I've got this piece of code to query a certain content type:

	var results = [];
  		$.ajax({
    		url: "https://blabla.sharepoint.com/_api/search/query?querytext='ContentTypeId:0x0100AEC702D446F8F04696C2B7573837C451*'&trimduplicates=false&rowlimit=500&selectproperties='FullName%2cWorkHours%2cWorkDate'",
    		method: "GET",
    		headers: {"accept": "application/json;odata=verbose"},
			success: function(xData, request){
            results = xData.d.query.PrimaryQueryResult.RelevantResults.Table.Rows.results;

This is working fine. But, as you can see it gives me all records (which can be a lot). In my current solution I build an If statement to filter "FullName" on the Current User. It works but performance wise is doe not seem the best solution. So I would like the initial query to give me only the records of the current user.

I tried several queries like this:

url: "https://blabla.sharepoint.com/_api/search/query?querytext='ContentTypeId:0x0100AEC702D446F8F04696C2B7573837C451*'&trimduplicates=false&rowlimit=500&selectproperties='FullName%2cWorkHours%2cWorkDate'?$filter FullName eq CurrentUser",

In all kind of different ways. But no luck so far.

When I have this in place I also would like to aggegate the hours per day.  But that will be phase two ;-)

Can someone help me out?
