Yes, that is the correct doc for the Java indexes. Regarding your GQL query, the name of the kind is not the full name of the class (including the package) but the simple name. So try using MDsIri instead of com.col.server. MDsIri. You should be able to see any entities you saved in the data viewer and the valid kind names are provided in the drop down.
