Question: When using a search engine to search, then would you use quotation marks around search terms?
Answer: Quotation marks should be used around a phrase or search terms. Surrounding terms with quotation marks limit the search results to only those web pages that contain the exact phrase, we have specified.
Doing this ensures that, the concept will be searched for as a whole and not picked apart by the search engine or we can say, without the quotation marks, the results will include any page that contains the words we have used regardless of what order those words are in 17. Transferring files through E-mail is restricted due to file size. Justify.
