 ### Chain
 
+- (feat) [\#1910](https://github.com/bandprotocol/bandchain/pull/1910) Implement request-search REST and CLI endpoint.
 - (impv) [\#1903](https://github.com/bandprotocol/bandchain/pull/1903) Store result in store instead of result hash.
 - (impv) [\#1901](https://github.com/bandprotocol/bandchain/pull/1901) Added `moniker` field to `delegations_view` table.
 - (feat) [\#1879](https://github.com/bandprotocol/bandchain/pull/1879) Keep `Request` and `Report` around. We avoid premature optimization at the moment.
