Altosax, unless you use a different string, the double + is not necessary, since that'd send the string something +anything +this +that +you +me to Google: Google by default uses all keywords entered (unlike other search engines).
In most search engines, searching this that will find pages containing this and that, pages with only this, and pages with only that.
Not so in Google: it always searches for all keywords, so you'll only get pages containing this and that.
The exception are so-called common words, if you _have_ to search the room, and not just room, you should use a + in front of it. So only in that case would using a double + be needed.
