PDF indexing: to also index a pdf document structure, such as bookmark

I dont think the plugin will index PDF file structure items such as bookmarks. This would be great if it did. That way, when a bookmark is indexed, and in the search result, it could preview/link to that bookmark/page of the document. This would be a great feature for larger publications so you didnt just get a whole doc as result and not know where that keyword is in the pdf document. If I am wrong please let me know.
If you have any further advise on maybe intergrating with something else out there to achieve this so I can use your plugin, I would be grateful.
