10 Search Engines to Explore the Invisible Web
The Invisible Web refers to the part of the WWW that’s not indexed by the search engines. Most of us think that that search powerhouses like Google and Bing are like the Great Oracle”¦they see everything. Unfortunately, they can’t because they aren’t divine at all; they are just web spiders who index pages by following one hyperlink after the other.
But there are some places where a spider cannot enter. Take library databases which need a password for access. Or even pages that belong to private networks of organizations. Dynamically generated web pages in response to a query are often left un-indexed by search engine spiders.
How do we get to this mother load of information?
That’s what this post is all about. Let’s get to know a few resources which will be our deep diving vessel for the Invisible Web. Some of these are invisible web search engines with specifically indexed information.
You can search by subject category and further tweak your search using the search options. Infomine is not only a standalone search engine for the Deep Web but also a staging point for a lot of other reference information. Check out its Other Search Tools and General Reference links at the bottom.
Intute also provides free of cost over 60 free online tutorials to learn effective internet research skills. Tutorials are step by step guides and are arranged around specific subjects.
For a really effective Deep Web search, try out the Advanced Search options where among other things, you can set a date range.
The domains covered by DeepPeep (Beta) are Auto, Airfare, Biology, Book, Hotel, Job, and Rental. Being a beta service, there are occasional glitches as some results don’t load in the browser.
Just like general web search, searching the Invisible Web is also about looking for the needle in the haystack. Only here, the haystack is much bigger. The Invisible Web is definitely not for the casual searcher. It is a deep but not dark because if you know what you are searching for, enlightenment is a few keywords away.
Do you venture into the Invisible Web? Which is your preferred search tool?

Deep Web (дословно "Глубокая паутина»)

Search engine technology has progressed by leaps and bounds. Today, we have real time search and the capability to index Flash based and PDF content. Even then, there remain large swathes of the web which a general search engine cannot penetrate. The term, Deep Net, Deep Web or Invisible Web lingers on.
