Foxit PDF IFilter 1.0.0. 3213(32-bit)

Foxit PDF IFilter is designed to help users to index a large amount of PDF documents and then quickly find text within these documents. The PDF documents can be files, email attachments or database records.

Foxit PDF IFilter supports up to PDF 1.7 specification and future versions can be used in the following environments: Windows Indexing Service, 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. Hereafter, we use term "search engine" to refer to these products.

Foxit PDF IFilter acts as a plug-in for full-text search engines. A search engine usually works in two steps:

Step 1, 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 PDF documents, in the background and creates internal data to store indexing result.

Step 2, 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 PDF document. Therefore, it looks in windows registry for an appropriate PDF IFilter and finds the Foxit PDF IFilter. Foxit PDF IFilter understands PDF format. It filters out embedded formatting and extracts text from the document and return text back to the search engine. Further information about IFilter specification can be found on the Microsoft Web site.
