Hi,

Within a indicator match detection, for the indicator index query are we able to modify how far that looks back within that index?

I spent a little time yesterday and it seemed to the do the trick. Both of the indexes are live, rather than 1 main index comparing against a threat intel source. Using this to help corrolate events from 1 alert source against a windows event log index.
