Simple Evolution Trick - Default searchtype

In Evolution, I use the search bar a lot, but the default is set to "Subject or Sender contains", whereas I always use "Message contains".

To set this as the default, go and edit the file /opt/gnome/share/evolution/2.2/searchtypes.xml

Look for the section ruleset , and within that section the rule with the title "Message contains". Cut that entire rule up until and including the closing rule tag, and move it up the ruleset section, just below the ruleset keyword.
Save the file and restart Evolution. Now "Message contains" is the default searchtype.
