Let me start out asking whether what I'm asking below has been asked before and if so where? So, I'm sorry to ask this but ...
1) Is it possible to search across more than one archive at a time?
[I don't see an obvious way to do this so I've been entering each archive and repeating my search.]
2) Is it possible to search for a phrase surrounded by quotations or perhaps another character?
[When I've tried this using quotations it will return the words I've used within my phrase but they are each word is separated by comma under the heading, "Containing Any of the Keywords:". Should I use "All" instead of "Any" within the option, "Only messages containing * of the following keywords:", if often won't return any results.]
3) Can I perform a search using boolean expressions?
[I'm probably pushing my luck even asking this. ;-) ]
