General Rules
* The query will search across both the full text and metadata of all HeinOnline documents, unless you otherwise specify a field such as “author”
* The query will look across all years available, unless a year/year range is otherwise specified
* Use quotes to form a phrase, “Right to Privacy” instead of Right to Privacy
* Use capitalized Boolean operators to combine search terms, for example: “intellectual property” AND “international law”

Phrase Search
To narrow our above query, let’s expand our term to a phrase, graffiti artist, and enclose it in quotations.
Example: “graffiti artist”
