a. Explain the use of the following search operators (+, - , “ “, *, AND, NOT, OR)
· The (+) and (-) are the operators which can be used in front of words to emphasize their presence (+) or elimination (-) while searching. For example if you were to search +university-library then the word university will be included in the search but the word library will be omitted.
· Quotation marks (“ “) are used when you want to search a phrase word for word. For example, if you wanted to search a quote but didn’t know the author, you would put the quotation marks around the quote and search to find the exact match.
· The asterisk (*) is an operator which can be used to match words in a phrase. This is an operator that looks for origins in spelling of words. For example if you were to search appendax* the search will return appendix and appendices.
· AND, NOT, OR are all types of Boolean searches. You would use OR when you want to search for pages that might have one of the several words searched. For example black OR white. When you use AND while searching it means that both the items are included in the search. For example when you search food AND drinks, it will search both the words. When you search using NOT it means that you want one word to be excluded from the search. For example hot beach NOT Sea, this means that the search results will only search for hot beaches and not seas.a.
