Microsoft Pdf Ifilter

Adobe PDF IFilter is designed for technically savvy users or administrators who wish to index Adobe PDF documents with Microsoft indexing clients. Adobe PDF IFilter is. Within Adobe PDF documents. Locate information IFilter is a. IFilter::BindRegion: Retrieves an interface representing the specified portion of object. Currently reserved for future use. IFilter::GetChunk: Positions the filter at the beginning of the next chunk, or at the first chunk if this is the first call to the GetChunk method, and returns a description of the current chunk. Sep 11, 2013 But most PDFs today are text based and fully index-able. OCR isn't a default for the iFilter on-premises either it is a custom install. The default iFilter used on-premises is the same one used in Office 365 and will index more than metadata if the PDF contains index-able text. The Sitecore Content Search API uses the native Microsoft Windows IFilter interface to extract the text content from media files for indexing. However, to enable the Sitecore Content Search API to properly index the content in Adobe PDF files, you must install the Adobe PDF IFilter on every content management and content delivery server.

When I do a search in Outlook via Instant Search, does Outlook then also search for the text within attachments such as pdf-files?

Control Panel for PDF Indexing Options Now click on Indexing Options / Advanced / File Types. This shows you the list of file extensions and the default Filter Handler registered for it. After installing an Adobe Filter, you can see that it adds a Handler for PDF that it calls “PDF Filter”.

Yes and no. While Instant Search does search within attachments, it cannot read all file types by default.

In order for Instant Search to be able to search within an attachment, an iFilter for that file type needs to be installed. Instant Search is using the Windows Search service built into Windows and can already index over 200 common file types by default.

iFilter for pdf-files

While pdf-files are being indexed, without an iFilter for pdf-files, Windows Search only indexes the file name for this file type.

If you are using Windows 8 or later, then you already have an iFilter for pdf-files installed since it is included with Windows.

If you are using a 32-bit version of Windows 7 or previous and have Adobe Reader or Adobe Acrobat installed, then you already have a proper iFilter installed and pdf-files are being indexed so you can also search within them with Instant Search.

If you are using a 64-bit version of Windows 7 or previous then, aside from installing Adobe Reader or Adobe Acrobat, you must also install this 64-bit iFilter for pdf-files. After installing the iFilter, the Indexer will begin to rescan your pdf-files and index the entire text instead of just the file name.

Depending on the amount of files on your disk, this indexing could take a while though so Instant Search will not directly start producing results after installing the iFilter. Leaving your computer running with Outlook open overnight should get the job done in most cases though.

Note: If a (pdf-)file only contains images of text (for instance a scanned document) and no OCR has been applied, then there is no actual text in the document which the iFilter can index.

More iFilters

If you need full text indexing support for another file type, then you can find several more iFilters here.

However, in case you need an iFilter for a specific file type, it is best to contact the vendor of the application that creates those files and ask them if they offer an iFilter themselves as well.

An IFilter is a plugin that allows Microsoft's 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 1]}LibreOffice, Microsoft Office^{[Note 2]} and OpenOffice.

It also refers to the software interface needed to implement such plugins.^[1]

How it works ^[2]^[3][edit]

An 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.g. a file folder or a database, and indexes all documents or newly modified documents, including the various types documents, in the background and creates internal data to store indexing result.
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 doesn't 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.

Search Engines[edit]

Windows Indexing Service and the newer Windows Search, Windows Desktop Search, MSN Desktop Search, Internet Information Server, SharePoint Portal Server, Windows SharePoint Services (WSS), Site Server, Exchange Server, SQL Server and all other products based on Microsoft Search technology support indexing technology. Also, IFilters are used by SQL Server as a component of the SQL Server Full Text Search service.

Notes[edit]
