Use the "+" in front of the words you want.
+index +average
in the search box will work, but keep in mind that the whole "branch" is
usually included in replies, so you will get more hits than expected...

I want to search all threads in
"microsoft.public.excel.worksheet.functions", containing two words Index and
average.
I tried many combination of two words, puting them in "message" box of
search windows but non of them worked.
How can I perform a search based on more than one key word?
