About IFilters, files type and indexing connector protocols (FAST Search Server 2010 for SharePoint)
Applies to: FAST Search Server 2010
Microsoft FAST Search Server 2010 for SharePoint can crawl content either by using the indexing connectors integrated in Microsoft SharePoint Server 2010 (through the FAST Search Content Search Service Application), or by using the FAST Search Server 2010 for SharePoint specific indexing connectors (the FAST Search Lotus Notes connector, the FAST Search database connector and the FAST Search Web crawler).
A number of indexing connector protocols are installed by default in SharePoint Server 2010, whereas other content sources require a different indexing connector and protocol which needs to be installed and configured separately.
All file types are crawled unless explicitly excluded. A number of file types with little relevance to search are excluded by default. You can find the file types that are excluded by default in the article IFilter and file type reference (FAST Search Server 2010 for SharePoint).
While most file types are crawled by default, FAST Search Server 2010 for SharePoint only provides filters for content and metadata extraction of a subset of them. The supported file types are listed in the article IFilter and file type reference (FAST Search Server 2010 for SharePoint). To extract content and metadata from additional crawled file types requires that you enable the Advanced Filter Pack or register a third-party IFilter.
