<div class="q" data-lang="neo4j">
Every Greek deity is known for having certain roles. The example shows the roles of '''Zeus'''.<br />
Note that strings (pieces of text that are data) should be either single or double quoted.
<p class="strong">
Find the roles of Hera.
</p>
<pre class="def"><nowiki>
MATCH (n)
WHERE n:God AND n.name = 'Zeus'
RETURN n.roles;</nowiki></pre>
<pre class="ans"><nowiki>
MATCH (n)
WHERE n:God AND n.name = 'Hera'
RETURN n.roles;</nowiki></pre>
</div>

<div class="q" data-lang="neo4j">
The '''IN''' keyword can be used to check if an item is in a list. <br/>
This simplifies expressions such as <code>x = a OR x = b OR x = c</code> down to <code> x IN [a, b, c]</code><br/>
The example shows a query that gets all the details of '''Hera''' and '''Zeus'''
<p class="strong">
Return all details of Apollo and Artemis.
</p>
<pre class="def"><nowiki>
MATCH (n)
WHERE n:God and n.name IN ['Hera', 'Zeus']
RETURN n;</nowiki></pre>
<pre class="ans"><nowiki>
MATCH (n)
WHERE n:God and n.name IN ['Apollo', 'Artemis']
RETURN n;</nowiki></pre>
</div>

<div class="q" data-lang="neo4j">
Operators can be chained together to check if an object is between two values.</br>
This changes expressions such as <code>a <= b AND b <= c</code> to <code>a <= b <= c</code></br>
The example returns all the names of any god who has a name starting with the letter '''A'''.
<p class="strong">
Return the names of the gods who's names start with a letter between E and J.
</p>
<pre class="def"><nowiki>
MATCH (n)
WHERE n:God AND "A" < n.name < "B"
RETURN n.name;</nowiki></pre>
<pre class="ans"><nowiki>
MATCH (n)
WHERE n:God AND "E" < n.name < "J"
RETURN n.name;</nowiki></pre>
