Bug 4074 Fix fail to parse simple qualified search

Searches such as au,phr and kw,wrdl were passing through the regexes
that should replace colon with equals
add wrdl and phr
use trn so not just rtrn is spotted
Where we were checking for multiple spaces specify that in the
regex not just two spaces
