That means that the search was truncated by a hash table hit.
A previous search was performed of the same position at equal or better depth
and stored in the hash table. When the search was performed for this iteration,
instead of performing the search again, the value in the hash table was used.
There is some information lost compared to a full search, because the entire pv
is not stored in the hash table.
