All time search should work right because this value of timerange will cover periodes includind periodes that your events have been produced.
So the best way is to use All time
It worked. Thanks. I can see the events now after changing the time range to 'previous year'.
But this is a random text file which I am using for some testing purpose. And it has data of last year. In this case All time search should work right?
no luck..when i type index=*, I am able to see all the events one with my source file also. But when i click on my source file, it again says 40events found. but says "no results found" under event tab.
