I had to change machine, from PC to Mac.
When I insert two "source words" for a TM lookup, I always get the no results found window, even though I know there are perfect matches. Without "" it works fine, but I get, as expected, too many results.
Please remember that TM Lookup is case-sensitive.
Also, try to have word+word (separated by a plus only) rather than the quote. This is another way for limiting the number of results; this means that both words should be in the segment.
But be sure that you do NOT have both "plus" and "quotes"; this will give you no result at all.
