It may seem easy to simply enter in a word or phrase and hit the search button, but did you know that there is so much work and technology behind such a simple thing? For over a century, there have been people who have worked very hard in designing systems for searching through literature etc. Out of all the literature and information that has come about in our world, there needed to be a way to be able to find a specific piece of information out of the giant haystacks of information, how to know where that needle in the haystack is. Several systems have been invented to keep track of where that needle is. Libraries use an index system to keep track of where specific books are, so that you or I could go into the library and ask for a book by subject, author, title etc and the library can look at their index and tell you right where the book is. This may seem simple, but to create that index is quite a challenge, imagine trying to create an index that keeps track of websites and webpages on the whole Internet.
A new field has come about recently and new careers are centered around this field, the field is called Information Retrieval. You may some day be getting your college degree in Information Retrieval. When it comes to the Internet, they have found that there are two different kinds of searches that could be performed, they are called Horizontal Searching, and Vertical Searching. Horizontal Searching is considered broad searching, for example: you are a doctor and you want to look up information on the Internet about skin, in a horizontal search about skin, the search engine doesn't know you are a doctor and the results from a horizontal search will be about many different topics about skin, in fact the first result that might come up might be a joke about sliding your friend some skin, but in all relevance, this is relevant to what you typed in, it's just not exactly the category you were shooting for, so this is why it's called Horizontal (broad) searching, it will bring you results about anything and everything about skin.
Vertical Searching is more specific, if you are a doctor and decide to run a search using a vertical search, you would type in the category you are shooting for and then type in the keyword you want to search for, for example: You would first type in Medical: then skin, like this - medical: skin , now the search engine knows you want skin results that have to do with the category medical and not humour, you must be a doctor. The vertical search would return much more relevant results to what you were looking for. Another way to understand Vertical Searching is to take a specific website for example: a medical website. The website is already categorized as medical of course, so if you (the doctor) searched on the medical site for skin, you know that the results will be medical and skin only, you probably wouldn't get jokes about sliding skin on a search of a medical website, but you probably wouldn't get any results at all about bananas, because you are strictly on a medical website, that's how vertical works basically, it means like searching a certain category. When you go to a library and ask for a book about bananas, they almost always ask you for a little more information on say what about bananas, what type of subject etc, you could say bananas business and then the librarian would know right where to take you. This is another way to view Vertical Searching, it is more refined and specific. So that's the difference between Horizontal and Vertical searching.
Wizimo can perform both kinds of searches, by default Wizimo will run a Horizontal Search, but if you add this character " : " without the quotes, this tells Wizimo to do a Vertical Search, the : is vertical so that's why we chose that symbol. To run a vertical search, the first word you type in is considered the category, then type :, then type whatever you are looking for in that category, so from the doctor example above, you would type: medical: skin. This tells Wizimo that medical is the category and to look for skin in the medical category. That's it, it's that simple. Try " internet: engine " and see what comes up, you will probably not even see one result about car engines.
You can also go further with categories, for example: " internet: search: engine " This will really bring relevant results for internet search engines.
