IMPORTANT NOTE: Starting with Acrobat and Reader 7.0.5, iFilter functionality is now bundled within the Acrobat and Reader products. Improvements to iFilter in Acrobat and Reader 8 include support for Vista and Windows Desktop Search, as well as improved performance and stability. It is recommended that you update your copy of Adobe Acrobat or Adobe Reader in order to get the most current iFilter functionality, rather than download and install the stand-alone iFilter plug-in.
Note: On February 18, 2004, Adobe posted a KnowledgeBase Document describing a known issue with Adobe® PDF iFilter 5.0 and Windows XP®. It is recommended that you read this document before installing Adobe PDF iFilter on this operating system.

IFilter is a Microsoft specification for filtering text. Further information can be found at:
Adobe PDF IFilter is a free downloadable Dynamic Link Library (DLL) file that provides a bridge between a Microsoft indexing client and a library of Adobe PDF files. It consists of code that understands the Adobe PDF file format as well as code that can interface with the indexing client. When an indexing client needs to index content from PDF files, it will look in its registry for an appropriate DLL and find the Adobe PDF IFilter. Adobe PDF IFilter will return text to the indexing client. The indexing client will then index the results and return the appropriate results to the user.
For all known issues, please reference the ReadMe file, which is included with the Adobe PDF IFilter.

Adobe PDF IFilter has no user interface and therefore is language-agnostic. It is tested and supported in Tier 1 languages (English, French, German, and Japanese), utilizing Tier 1 operating systems and Tier 1 text within Adobe PDF documents. However, it has also undergone additional limited testing utilizing Adobe PDF documents in all Acrobat languages and correctly returns text to the Microsoft indexing client. Since the Adobe PDF IFilter is based on the Microsoft indexing client, it is this indexing client that is responsible for interpreting the returned text and then presenting the information to the user.
