Query
A keyword, group of keywords or phrase, with or without special instructions like Boolean operators, used in a search. In simpler terms, it is that which the user enters into the search box. It is what the search engine compares documents to in order to return only relevant documents.
Quote(s)
When used in a search, the quote marks ´ " ´ tell most systems that you only want to see matches that are exactly like what you are asking for. For example, a search for ´electric light´, entered without the single quotes, will return much different results than "electric light" entered with the quotes as shown.
