If you have events want to select or group by and then limit the number of matching events or values (for example the top or bottom 5 rows), there are a few options available:

The tokenHash() function creates a hash of the string, or more specifically the basic form of the string. You can either do this the entire event:

hash := tokenHash(@rawstring)
| groupBy(hash,function=tail(1))

This creates a hash based on the event value and outputs just entry for each matching hash; that event value could then be used to identify the list of events.

This solution has the advantage that you dont ned to identify the individual fields that you want to search/select by.

If you want to be more specific, create a create made up of identifying values and then group by that value:

entryident := format("%s%s%s",field=[#kind,#repo,#type])
| groupby(entryident,function=[count()])

You can add a head() or tail() to limit the list.
