I'm trying to set up a search on eBay to give me a list of 7.5 or more digit multimeters, but all I get is crap based on my second numeric search term. I'm trying to use a string like this:
(HP, Agilent, Keysight, Keithley, Hioki, Advantest, Guildline, Datron, Prema) AND (34470, 3458, 7510, 2002, 2001, 2010, DM7276, DM7275, R6581, 7081, 7071, 9578, 9577, 1281, 1271, 8017, 5017, 6048, 6047, 6040S) -manual
I was under the impression that words in parentheses were a logical or and maybe it is, but it does not seem to honour the AND condition. Can anyone tell me how to make the eBay search return what I actually want?
