When executing FT.SEARCH, FT.AGGREGATE, FT.CURSOR, FT.HYBRID, TS.MGET, TS.MRANGE, TS.MREVRANGE, and TS.QUERYINDEX while an atomic slot migration process is in progress, the results may be partial or contain duplicates
FT.PROFILE, FT.EXPLAIN, and FT.EXPLACINCLI do not contain the FT.HYBRID option
Metrics from FT.HYBRID command are not displayed on FT.INFO and INFO
FT.HYBRID: the EXPLAINSCORE, SHARD_K_RATIO, YIELD_DISTANCE_AS, and WITHCURSOR options are not supported
