Dear Sri Deepak Singh,
Thanks for your mail.
Search Engine is a single entity search tool while, as par Wikipedia Meta Search Engine "....is a search tool that sends user requests to several other search engines and/or databases and aggregates the results in a single list or displays according to their source....."
AND and Or are boolean logics to compose search strategies more precise. As for example, if you have two key words Bread & Butter and you want search based upon two key words and formulate a search like Bread OR Butter you will receive all references (available on that particular database) relating to Bread only and relating to Butter only and those where both the key words (Bread & Butter) appear.
But if you search the same database with the search Strategy Bread AND Butter you will retrieve ONLY those references where BOTH the key words appear.
Now, say in that particular database there are 500 references with the key word with bread only and
300 references with the Key word with Butter only and
200 references comprising both the key words Bread and Butter
Tthe first search (Bread OR Butter) will thus provide you with 500+300+200 = 1000 references
While the second search (Bread AND Butter) will provide you with only 200 references.
I hope I could explain the issue.
Regards,
Siddhartha S. Ray, Calcutta
