Hi Alfred, Thanks for clarification. I also have 2 questions:
1. For this query: SELECT * FROM Model WHERE list = :1 AND list =:2 AND list=:3 AND string :=4 ORDER BY date DESC will be enough this index? - kind: Model properties: - name: list - name: string - name: date direction: desc 2. After I create this index (or indexes) I will still receive this exceptions? com.google.appengine.api.datastore.DatastoreNeedIndexException >> The built-in indices are not efficient enough for this query and your data. Please add a composite index for this query.. An index is missing but we are unable to tell you which one due to a bug in the App Engine SDK. If your query only contains equality filters you most likely need a composite index on all the properties referenced in those filters. --Alex -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
