for my assignment 1, i had choosen impact of budget airlines in asia. during my time doing the research on this topic, i have understand the different types of search facilities. The Search Engine, Meta Search Engine and subject directories. For me, i would use Search Engine to search for information, this is my favourite search facilitiy.
Search Engine: Eg- http://www.google.com/
the search result from Search Engine are very high because they have their own database. it can go up to 1 million results but it does not take a long time to search. the search engines also allows us to search more easily because of the phrase we search.
Meta Search Engine: eg- http://www.metacrawler.com/
the search result is much more lower as compared to the Search Engine. they uses database form other search engines therefore the results shown are much more lesser.
Subject Directories: eg- http://dir.yahoo.com/?skw=yahoo+directory
the search result are lesser than Search Engine but more than Meta Search Engine. this search facility is not suitable for searching an specific issues (eg:cyber crimes). it is more suitable for searching common topics then close in on more specfic topic (eg:terrorist)
