Unable to create an exact copy of the "AuthorOWSUSER" in search managed property

Question

I am working on a Team site collection inside sharepoint enterprise server 2013 and I have added a Content Search web part. Now I wanted to show the CreatedBy field inside my content search web part. So I find that the intended managed property is "AuthorOWSUSER", as follow:-

I chose this specific managed property since this managed property shows the original creator of the item, unlike the "Author" managed property which shows the creator + any user who modifies the item..

The only issue I faced with the "AuthorOWSUSER" is that I am using a custom display template , and this custom display template uses the managed property name as a title inside the generated list as follows:-

So i wanted to rename the "AuthorOWSUSER" to something which is more user friendly. I did the following steps to create a new copy of the "AuthorOWSUSER" managed property, with a new name. I went to "Central Admin">>"Search Service">>"Search Schema">>"Add new managed property">> I named it "Creator" and I defined the same setting as which is provided inside the "AuthorOWSUSER" . But the result I got for the new managed property is that the whole user details such as user id , domain name will be shown , unlike the "AuthorOWSUSER" which will only show "FirstName LastName",

So can anyone advice on this please ? How to create a copy of the "AuthorOWSUSER" with new name ? I know that I can rename the original "AuthorOWSUSER" to be "Creator" but I always try not to rename or remove any things which is provided by default inside SharePoint , such as the "AuthorOWSUSER" managed property..

Hint. Now i have noted that inside my new managed property I am unable to change the "advance searchable settings". Now inside the built-in "AuthorOWSUSER" the full-text index is set the "default" , while on my new managed property it is set to "peopleidx" and I am unable to change it ,so could this be the problem, that on the new managed property the full name details (including id, domain, etc) will be shown ?

Answer 1

there are 2 options -

1) in your custom display template, find the ManagedPropertyMapping section, in that you can add/edit the mapping as below. Its called mapping the property:

  'Author':'AuthorOWSUser'

This should change the title. Its like display name / internal name mapping.

2) or in the display template code, you can extract the author value as follows:

if (!$isEmptyString(ctx.CurrentItem.AuthorOWSUSER))
        {
            author = Srch.U.getDisplayNameFromAuthorField(ctx.CurrentItem.AuthorOWSUSER);
        }

or like this

 var author = $getItemValue(ctx, "Author");

This will give you the correct author value.

Edit :

Based on the comments, i am adding the below code which will rename AuthorOWSUSER in the title:

in your display template , find this line and change it as below:

        // Show the properties that aren't empty
    for(var i = 1; i <= 10; i++) { 
        var property = $getItemValue(ctx, String.format("Property {0}", i));
        if(property.managedPropertyName !== String.format("Property {0}", i)) {
            var propertyName = typeof propertyNames[property.propertyLookupName] === "undefined" ? property.managedPropertyName : propertyNames[property.propertyLookupName];
            if(propertyName =="AuthorOWSUSER"){
                propertyName = "Author";
            }
