Why does it say 21/438 in my search field but only 2 results displayed

This could well be because other results are showing as junk. Check your filter>junk in options, and get it to show junk files. They will show beside a trash bin.

An other possibility is that you are seeing one file with the number of hosts as 11, and another with 10 hosts, so available files is 11+10 =21 but you will just see 2 files in the search tab

I hope this helps
