Search on "file changed after" mask problem

On a Synology NAS (DSM) I wanted to search from root for all files changed the last day. I tried various masks but the search results seem to include files with all kind of change-dates (didn't wait for completion) The mask to exclude small files seems to work.

>2015-07-05;>5K
*>1D; >5K | /volume1/

The *>1D is the correct mask to use. But if you want to combine that with a size constraint, it's *>1D>5K.

The *>1D; >5K means all files modified in the last day or larger than 5 KB.

Thanks, I'll try it. Apparently I missed this in the manual/hints or maybe it wasn't stated there
