|TermTitle||SharePoint||According to the documentation this is the title of an item in SharePoint but in my environment it is not filled in for any item. In my experience you can move this crawled property down in the priority for the managed property|
|Office:2||Office||Office:2(Text) crawled property maps onto Title property which is used in the Word document itself as part of the summary information|
|ows_BaseName||SharePoint||Name of the SharePoint page|
|Title||DocParser||Title as picked up by the content processing component|
|MailSubject||DocParser||The subject of an email file as picked up by the content processing component|
|Mail:5||Subject line of an email file|
|People:PreferredName||People||PreferredName property in the SharePoint user profile|
|Basic:displaytitle||Basic||Filename of Office document|
|ows_Title||SharePoint||Maps to SharePoint list field Title|
|Basic:10||Basic||Mapped to Title,FileName|
So if you want to be sure that the title of the an item is used in SharePoint search result, you can move the ows_Title crawled property before the MetadataExtractorTitle property. If one of the crawled properties is empty, the next crawled property will be used. This means that if the user does not specify a title in SharePoint, SharePoint will try to use metadata extraction for Word and PowerPoint files to give a an alternative for the title.
Unfortunately, you will need to perform an index reset first and afterwards you will need to do a full crawl to see the result of your changes.
