Not all metadata properties extracted from a file are marked with tags.

The following example demonstrates some advanced usage scenarios of the GroupDocs.Metadata search engine allowing to remove metadata properties....app conholdate.com conholdate.cloud conholdate.app containerize...
Stop words are frequently used words that do not carry a semantic meaning and can be removed from an index to reduce its size.
