You can extend Windows Search to index new or proprietary file types by writing filters to extract the content, and property handlers to extract the properties of files. The IFilter interface is designed to meet the specific needs of full-text search engines.

Full-text search engines like Windows Search call the IFilter methods to extract text and property information and add them to an index. Windows Search breaks the results of the returned IFilter::GetText method into words, normalizes them, and saves them in an index.

If available, the search engine uses the language code identifier LCID of a text chunk to perform language-specific word breaking and normalization.

Filter handlers must be written to manage buffers, and stack correctly. All string copies must have explicit checks to guard against buffer overruns. These indices are used to return your search queries. When you search for a particular string or phrase, the Index Server returns all the documents that contain the string or phrase.
