Please check out the below code, I would like to show users a previous search
history and everything seems to work ok except that on the first time through
it appends the seach phrase twice. I understand why it is happening, (due to
the 2nd conditional statement) but cannot figure out a better way. Maybe
someone can test it out for me, and give me a pointer. Thanks a bunch!!!
