After insert we can view all nodes and their relationship

UseCase - Search as you type

When I start typing my symptoms Then matching symptoms are returned in alphabetical order.

MATCH (s:Symptom)
WHERE toUpper(s.name)=~ toUpper('c.*')
RETURN s.name AS `Symptom`
ORDER BY s.name ASC

UseCase - Get all symptoms

To Get all the Symptoms

MATCH p=()-[r:MAY_MANIFEST_SYMPTOMS]->() RETURN p LIMIT 25

UseCase - get all physicians

Get all Physicians and their speciality

MATCH p=()-[r:SPECIALISES_IN]->() RETURN p LIMIT 25

UseCase - get all physicians filter by speciality

Get all physicians for one speciality

MATCH p=()-[r:SPECIALISES_IN]->(s:DoctorSpecialization) WHERE s.name = "Angiologist" RETURN p LIMIT 25
