IFilter Wikipedia. An IFilter is a plugin that allows Microsofts search engines to index various file formats as documents, email attachments, database records, audio metadata etc. so that they become searchable. Without an appropriate IFilter, contents of a file cannot be parsed and indexed by the search engine. They can be obtained as standalone packages or bundled with certain software such as Adobe Reader,Note 1Libre. Office, Microsoft OfficeNote 2 and Open. Office. It also refers to the software interface needed to implement such plugins. 1An IFilter acts as a plug in for extracting full text and metadata for search engines. A search engine usually works in two steps The search engine goes through a designated place, e. A user specifies some keywords he would like to search and the search engine answers the query immediately by looking up the indexing result and responds to the user with all the documents that contains the keywords. During Step 1, the search engine itself doesnt understand format of a document. Therefore, it looks on Windows registry for an appropriate IFilter to extract the data from the document format, filtering out embedded formatting and any other non textual data.
