-Query data in any table against data from a watchlist by treating the watchlist as a table for joins and lookups. When you create a watchlist, you define the *SearchKey*.

+Correlate your watchlist data against any Microsoft Sentinel data with Kusto tabular operators such as `join` and `lookup`. When you create a watchlist, you define the *SearchKey*. The search key is the name of a column in your watchlist that you expect to use as a join with other data or as a frequent object of searches.
