}

Description

• None: Search all

• KeysOnly: Search Key only. It cannot be used together with ValuesOnly, DeserializeValues, PickField0, and PickField1.

• RemovePrefix: Similar to KeysOnly. It will filter to the first byte of Key, i.e., the prefix of Key. It cannot be used together with ValuesOnly

• ValuesOnly: Search Value only. It cannot be used together with KeysOnly and RemovePrefix.

• DeserializeValues: Search Value and then deserialize the Value.

• PickField0: Search the first element of Value array. It must be used together with DeserializeValues, not with PickField1.

• PickField1: Search the second element of Value array. It must be used together with DeserializeValues, not with PickField0.

• FindOptions is used in Storage.Find(StorageContext, ByteString, FindOptions)
