Not really, but a combination of:

	[page href=scan arg="
							co=yes
							sf=list_date
							sf=list_date
							se=199608
							se=199704
							op=ge
							op=le
						"]

is the same as a range look.

But without some qualifying info for a regex match it can be very slow as it
has to examine every line.

Best is to index and use the dict_look binary search. I have finally
put an example of that on the 3.12 index.html (the leftside file to
be exact). Note that it works in conjunction with this line in
catalog.cfg:

Database products INDEX category

You would add something like:

Database products INDEX category list_date

Now

	[page href=scan arg="
							dl=199608
							di=list_date
							de=199705
						"]

should do the trick (order is important here, read the docs for why).
Or for sure:

	[page href=scan arg="
							dl=199608
							de=199705
							fi=products.asc.list_date
						"]
