Search Engines
Search engines can only search a third of all the printed matter on the internet.
This is because the pages supplied by search engines databases are gathered by computer robot programs called spiders.
The robots cannot think and so can only supply you with web pages that are already on their databases or trawl
through the links embedded in these documents to provide additional information.
Searching by keyword is appropriate for these files because they are indexed using all the words or text contained in the web pages including
title, the URL and embedded links within the file. They are usually sorted by how many times they have been visited rather than by relevancy
There's no censorship or quality control, so results need your careful evaluation.
The pages and links excluded from search engines are called the "invisible web". So it is important to use more than one search engine
or use subject directories to enable a comprehensive search.

Meta Search Engines
These search other search engines’ databases all at the same time.
Good for quick and simple keyword searches, but not very thorough.
- Kartoo is a new metasearch engine that displays its results
as a concept map. This can be helpful if you are trying to make connections between subjects or ideas.
As soon as you launch a search, Kartoo analyses your request, questions the most relevant engines, selects the best sites and places them on a map.

Subject Directories
Subject directories, unlike search engines, are created and maintained by specialist
human editors.
As the information is hand-selected and evaluated following a selection critieria
the pages are more specific, relevant and of higher quality.
The directories are organised by subject in a hierarchal structure and indexed accordingly.
Keep search terms broad as you are not searching the full text of pages but searching by subject and
or meta data. You may need to search a number of directories depending on their focus.
HINT! a number of search engines have an inbuilt directories which you can access
by making the word "directory" part of your search term.

Specialised Databases (The Invisible Web)
A large percentage of all internet web pages cannot be found by search engines
because they are not stored on search engines databases but are generated on request from specialised databases.
However you can find searchable databases and other "invisible" pages by using web directories.
or by using the term "databases" as part of your search term, eg "volcano database" while
using search engines such as Google and Yahoo.
