When using the GUI you can choose custom time off the timepicker and select specifically earliest and latest date. or you can specify directly in your search:
sourcetype= something earliest=-5d@d latest=-1d@d

I already know this.
I want to see 30 days before and 30 days after a date.
If I put "03/03/2016," the system will look for 30 days before and 30 days after the date that I put.
The date "03/03/2016" will not be fixed.
But I always have to search data 30 days before and 30 days after the date I choose
You want to specify a latest time of "-1d@d". The specifics of how to do that depend on how you're using "-3d@" today. You could, for example, modify your search string to
... earliest="-3d@" latest="-1d@" | .... For saved searches, put "-1d@" in the "Finish time" box.
It'll depend upon how you specify the time range for your search, either using time range picker OR directly specifying time range modified in the search.
If you specify the time range modifiers directly, use below for yesterday to 3 days ago from yesterday
If you use time range picker, either you can use above using the 'Advanced' tab of time range picker, OR you can use this subsearch method to override the timerange picker selection. Assuming you're selecting your 'Reference date' in time range picker (either using preset to select Yesterday OR Date range to select exact date).
