This appendix is a brief introduction to the operators and functions supported by Cypher 2.0.1. For each operator or function, we will see a brief description, an example, and some usage notes.
The queries are performed on an example database of books that have labels and relationships described in Chapter 2, Filter, Aggregate, and Combine Results. Sometimes, I used the HR management tool database (from Chapter 1, Querying Neo4j Effectively with Pattern Matching) when it would be more appropriate.
To try out the code, you can set up the database with the scripts, which you can download from the Packt Publishing website (http://www.packtpub.com/support).
