Foxit PDF IFilter

Search PDF documents anytime, anywhere. That's the promise with this plug-in tool and that's what it's done.

When there's need to find specific text fragments or even single word among lots of documents you usually use a search engine. You normally enter the search keywords, push the button and in a few seconds a list of documents matching your criteria shows up. Well, when you want to do that including PDF documents in the searching process, you need this software. Why is that? Because standard search engines doesn't understand PDF language so they need a “translator” to help them up.
So, how does the indexing process work? The reason you get results so fast when you search for a specific text in hundreds, maybe thousands of documents is the previous indexing process that took place. Search engines divide work into two tasks: indexing and searching. In some predetermined times it performs the indexing process automatically, and save the index files somewhere. What those files contain are “specific directions” to specific results (in this case, results would be words). This way, when you enter search criteria, the engine looks up for the criteria within the index files and not the documents themself, wich of course is much faster. The net result of this work division principle is less waiting time for you.
Since this tool is an assistant for the search engines, working in the shadows, doesn't have a visual interface. In fact, after installation, all you're going to see is a Readme file containing some information. When we talk about “search engines” we are referring to products like: 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.
There two versions of this tool, the 32-bit and the 64-bit. Wich one you need depends upon the system you are working with.
If you are asking yourself how much does something like this cost, let tell you about that. The license cost is according with the amount of servers where you will be doing searchs. The beginning price, for each server with up to two CPU cores, is 329,99 dollars. From there, each additional CPU core costs 129,99. Right now is a promotion going on that can save you up to 30%.
Maybe it's not exactly a cheap tool but you should aks yourself how much does it cost for the company the time spended on searching tasks.

A tool that fully integrates with systems running on your company.
