For something like this, i would think you would want to use an egrep or grep expression. I dont think (or dont know how) to use a variable passed into Awk as a pattern to search. But you can do something like this, thought it may not run too fast.

Code:
awk -v ph=bbb 'BEGIN{ FS="|" ; OFS=" " } {if($1 ==ph) {print $2, $1}} ' file

If I read the question right....

Code:
awk -v ph="bla bla bla" 'BEGIN{ FS="|";OFS=" "} /aaa/{print $2, ph}'  file
