Week 4 and 5

Through the activity done in week 4, I learnt that there is different search facilities and they are search engine, meta-search engine and subject directory. Moreover I learnt that there is different function in the 3 search facilities and is able to aid me in doing research in a must faster and efficient ways.

CONCLUSION
One of the main differences of all 3 search facilities how the result is generated. Search engine find matches to the searched term and generate the result. Meta search engine uses other search engine such as google and yahoo to find the result. Then it compiles the best results and deliver it for user. While subject directories, it generate result from the searched term but is not very effective. For example, searched term is “usage of blogging in business” the result generated might just be about Blog or categorize to different kind of blog.

The second differences are the search capabilities of the 3 search facilities. Search engines are able to generate millions of results and results are listed down in order of whether website is relevant to search topics. Therefore, I could say the search capabilities of search engines are very effective.
As for Meta search engines, it can give the best results as it actually compile all the results from different search engines and thus, results deliver are comprehensive and relevant.
Lastly for subject directories, the searched capabilities are not very effective as it could not give relevant information of topic search.

Overall, I would feel that Meta search engines are the most effective and best search facility among the three. Basically, it helps me to find the resources of the research topic. More importantly, it provides me with relevant website although it had only 59 results compare to search engines of 3,300,000 results. Search engines are capable of generating so many results, but not all results are relevant. Another plus point for Meta search engines is that it takes the results generated by the world leading search engine and deliver it for user.
