How do I actually put data inside the page cache?

Quoting the documentation, each file in the Neo4j store is accessed through the Neo4j page cache. So I take that every time a query happens the page cache will be accessed, right? I've tried adding an example graph (like The Movie Graph), then executing example queries through the web interface like

MATCH (bacon:Person {name:"Kevin Bacon"})-[*1..4]-(hollywood)
RETURN DISTINCT hollywood

So why is that that when I check :play sysinfo it still says No statistics available. under Page Cache?

By the way, I also went to conf/neo4j.properties and set dbms.pagecache.memory=2g (also removing the # comment mark), because I assumed it is required that I define a value for the page cache memory.

The data is always accessed through the page cache, even if you haven't explicitly configured a size for it. The page cache statistics in :sysinfo are just not available in the Community Edition of Neo4j.
