How to correctly create index for subquery in couchbase server?
How to do correct index for that query? I need to speed up this query.
SELECT q1, q2
LET q1 = (Select ht.* FROM `mybucket` as mb WHERE mb.recdate IN (SELECT RAW MAX(recdate) FROM `mybucket` as mbt WHERE mbt.deviceID = "10101")),
q2 = (Select ht.* FROM `mybucket` as mb WHERE mb.recdate IN (SELECT RAW MAX(recdate) FROM `mybucket` as mbt WHERE mbt.deviceID = "10001"));

You have two parallel queries, each with a subquery. The two queries are very similar.
You might be able to do this with two indexes.
This one should fit the subquery in each case:
CREATE INDEX date_deviceid_idx on mybucket(deviceID, recdate)
And this one should fit the main query in each case:
CREATE INDEX ht_recdate_idx on mybucket(recdate, ht)
