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.
