It's not simple, but once you've done it, it's easier....
click in the search bar (upper right)
SEARCH TOOLS appears in menu
select SEARCH TOOLS icon, which creates a pull down
select ADVANCED FIND
once open, click ADVANCED tab
down to click FIELD and select from the pull down DATE/TIMES and from the next pull down RECEIVED
then in the next panel to the right RECEIVED
and enter a data range...
I don't recall how to format this, but it can be done, so keep experimenting.
click ADD TO LIST button.
[you might be able to create two ranges, but I don't know if the two are treated as an OR or an AND]
Note that you can only search on one folder at a time.
I've always been able to search all subfolders when I select a parent folder, but that might require a choice somewhere else... a choice I made once in 2003 and never had to do again....
It can't search to parallel folders at the same time...so, it can't search your root .pst folder AND an inbox...those require 2 searches.
Wow! That does sound complicated, but I've been doing advanced searches for so long it does get easy...
