A program that searches documents for specified keywords and returns a list of the documents where the keywords were found.
How do search engines rank the stuff they find on the internet?
The search engine lists the results according to how relevant they think it matches the search query. However sometimes the results returned have minimal relevance to the search query.
who, or what, makes one page (that you might get in your search results) more useful than another one, so that it is put at the top of your search results?
Results are listed on the top of your search results if they position the keywords in a sentence form so that the relevance to the query is clearly visible.
what are some of your favourite search engines? why do you like one more than others?
I normally use Google for searching because i find that the search results are more spot-on and the image search is quite handy and loads quickly. However i have started to use other search engines since commencing this course.
Can you find some current news stories about search engines? (for example, Google has been in the technology news a bit lately).
