You may also have a look at the last use dates.
An index which was not used for a long time may no longer be used.
If an index is only used sparingly for statistics you may decide if you want
to keep it or not. Statistics collection is then just a little slower.

Thank you Birgitta. That is exactly what I was looking for. Fortunately
there are not many indexes with query_use_count = 0 and
query_statistics_count = 0
