Original description

Hi All.
I have got java application.  This is application uses Relational DBMS - PostgreSQL. It has got hierarchical structure data. Relational DBMS is bad makes recursive query, so I want to replace Relational DBMS  on NoSQL database.I estimated a OrientDB and I think that is best choice for this.
I have got few question.
1. You show example as make query
List<ODocument> result = db.getUnderlying().command(
  new ONativeSynchQuery<ODocument, OQueryContextNativeSchema<ODocument>>(&quot;Person&quot;,
                                                new OQueryContextNativeSchema<ODocument>()) {
    @Override
    public boolean filter(OQueryContextNativeSchema<ODocument> iRecord) {
      return iRecord.field(&quot;city&quot;).field(&quot;name&quot;).eq(&quot;Rome&quot;).and().field(&quot;name&quot;).like(&quot;G%&quot;).go();
    };
  }).execute();
But it don't work. My IDE show that is mistake. How I can make this query?
2. How I can make recursive query for graph?

PS Sorry for my bad English.
Thanks.
