Type of Search facility	Keywords used	URL of the resource	Comments on Search Results : -Size of hits? -Relevant results?

(0.10 seconds) Out of so many results, most of the first few results are relevant. It gives many related results based on my keywords. Some of the relevant results include the two factors authentication for banks and different kinds of online banking and company.

Subject Directory Example used :	http://search.yahoo.com /search;_ylt=A0oGkivSV T1HomUAyVpXNyoA?p= two+Factor+Authentication +in+bank+&fr=yfp-t501&ei =UTF-8&fp_ip=SG&rd=r1& meta=vc%3Dsg Two Factor Authentication Bank	http://www.comodo.com/ banking/twofactor.html	1-10 of 993,000 for two Factor Authentication in bank (About) - 0.36 sec Only some of the results are relevant. Some of the results are websites that have only one of the keyword. Some of the relevant results include reports from personal websites that gives information on the keywords.

The results of the three search facilities are almost the same because the keywords that I used are phrases and are quite specific.

Metacrawler.com gives more detailed because it combines both the search engine of google.com and subject directory, but it has lesser results than the google.com and yahoo.com.

Another differences is that both google.com and yahoo.com finds website using all the words that are typed in as the keywords while metacrawler.com used only one word that is typed as the keyword when finding results.

Yahoo.com may find some results that are same as the other two search facilities but the other results that it searches are not relevant. For example, when I typed the two factors authentications of bank, it gives me some results that are related to banks and not the two factor authentication.

Out of the three search facilities, google.com finds the results the fastest and gives quite relevant results.

Overall, I think that google.com has the best searching needs because it searches for the most relevant results and has many choices of websites from the result to choose from.

The results are based on the keywords that I wanted to find and gives not only a list of banks of two factor authentication but also online and banking related to two factor authentication.
