Applies to: FAST Search Server 2010
The item processing pipeline prepares an item from a content source for indexing and searching. This preparation includes text extraction, language detection, and tokenization.
Some applications may require extensions to the item processing. You can generate additional searchable metadata from the content, or forward a piece of information from the item to a third-party application for statistical or monitoring purposes.
For more information, see Integrating an External Item Processing Component on MSDN.
