how to display Title in properties of PDF file instead of file name

as the title, could you show me how to config system to display the Title of PDF file instead of display file name.

I know that, when the search result display html file, they should show the title of html file instead. That’s the meaning result.

At the moment, properties info of a file is available with a dynamic field,
but it is not displayed as Title.
To display it as Title, it will be fixed in the next release.
