List Expressions, UNION, and Subqueries

We have looked at filtering and sorting in Cypher queries in earlier chapters. In this chapter, we will take a look at more advanced options for querying.

We will cover the following topics:

• Working with list expressions
• Working with UNION in Cypher
• Working with subqueries

Now, let us take a look at list expressions.
