Agreed that the search mechanism is not a brilliant piece of engineering :-)
It takes some time to get used to its quirks.
It works, though, if you are satisfied by full text search, plus some
more criteria (basically years/issue numbers, if I remember well).
If you want a more advanced mechanism, though, you are out of luck.
It would be nice to have a way of updating the DVD edition every 2-3 years.
I haven't got any e-magazine copies (I still prefer to get the hardcopy
print version - if the e-magazine is appreciably cheaper, I may bite -
and my renewal time is approaching)
I am seriously thinking of ordering the MR DVD edition myself. I have
stopped getting the regular issues.
