sys.col_usage$ question

Maybe I am being little bit clueless (blame that on Eggnog) but what's
the difference between the columns equality_preds and equijoin_preds
in sys.col_usage$??

Has anyone attempted better indexing methodology based on this table?
We have got a bit of re-engineering going on and came to this table
when analyzing index usage.

TIA
