In our live environment, there are many searching and indexing within a millisecond. we used facet and sorting in Query.
> 3. To speedup sorting have a separate field with docValues=true for sorting. Is it necessary or useful to make a separate field if I used this field in sorting or facet? If I do not do a separate field then any performance issue when the same field will search in a query?

It doesn't make sense to have a sort on "id" in descending order twice. 2. Be aware that the id field has the highest cadinality. 3. To speedup sorting have a separate field with docValues=true for sorting. E.g. <field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" /> <field name="id_sort" type="string" indexed="false" stored="false" docValues="true" useDocValuesAsStored="false" /> <copyField source="id" dest="id_sort" /> Regards Bernd Am 10.05.19 um 15:32 schrieb vishal patel: > We have 2 shards and 2 replicas in Live environment. we have multiple > collections. > Some times some query takes much time(QTime=52552).
