 * You have created a query that contains a xref:select-statement/index.adoc[`SELECT` statement] that uses a xref:select-statement/index.adoc#_path_pattern[path pattern] in its `FROM` clause with one or more hops.
 * You have the privilege to install queries on the graph where you are operating.

 In other words, it specifies the structure of paths to be matched, without specifying the particulars of how the graph is traversed to find these paths.
 It is the query optimizer's job to determine the best graph traversal plan to satisfy the query.
