Manual index rebuild

Is it possible to manually rebuild the dgraph index?

I’m having problems where a query will be working one day, and a few days later the exact same query returns nothing, even though no new data was added.

BTW, this has been a problem I’ve seen ever since upgrading from 1.0.x and I’ve tried all the versions up to current beta.

Drop all indexes via Alter, and send again the same Schema to Alter so you recreate the indexes.
