Tips Writing a query is a way to ask a question about a subject.
The way you ask questions in the form of queries determines which documents will be returned. The simplest way is to enter words that describe the subject you are interested in. The most relevant documents will appear at the top of the results list. You can make your queries more specific by combining the words you used for basic queries with operators. Operators are special words that are used to indicate logical relationships between the descriptive terms that make up your query.
