Delete an index
Required arguments
index
is full-text index name. You must first create the index using FT.CREATE.
Optional arguments
DD
drop index operation that, if set, deletes the actual document keys. FT.DROPINDEX index DD is an asynchronous operation.
By default, FT.DROPINDEX does not delete the documents associated with the index. Adding the DD option deletes the documents as well.
If an index creation is still running (FT.CREATE is running asynchronously), only the document hashes that have already been indexed are deleted.
The document hashes left to be indexed remain in the database.
To check the completion of the indexing, use FT.INFO.
Return
FT.DROPINDEX returns a simple string reply OK if executed correctly, or an error reply otherwise.
