Ok, demo table contains patients demographic and administrative information (age, sex, etc.) and drug table contains information about drugs used by patients.
The relationship beetween demo-drug is 1-n (drug contains more vertices). I don't understand if it is correct to use 'expand' rather than 'traverse' and sincerly I don't understand how 'traverse' works. I try to use 'parallel' because I think it is useful with a quad core processor and the result is better, but it is not always so, for others sample queries it is not sufficient.
