Subject Re: Oak Property Index Question
Date Fri, 14 Mar 2014 21:25:26 GMT
Thanks for your response, Davide, I did get the propertyIndex to work!

I have one question however:
I can only get the query to work when querying for nt:unstructured, but
not for nt:base. Is this the expected behaviour?

I can create my index either with the „declaringNodeTypes“ property set to
„nt:base“ or with the property omitted:

Node propertyIndexNode =
session.getNode("/oak:index").addNode("testIndex",
"oak:QueryIndexDefinition");
            propertyIndexNode.setProperty("type", "property") ;
            propertyIndexNode.setProperty("propertyNames",
"trainingProperty");
            propertyIndexNode.setProperty("declaringNodeTypes","nt:base“);
// can be omitted
            propertyIndexNode.setProperty("unique", false);
            propertyIndexNode.setProperty("reindex", true);

In both cases the following query is using the index:
SELECT *  FROM [nt:unstructured] WHERE trainingProperty = 13

But the following query is not:
SELECT *  FROM [nt:base] WHERE trainingProperty = 13


Thanks,
Ben
