TIP: Searching this Forum for occurence of a word...

[(X)]

I just realised that searching this forum for a word that contains an underscore "_" will fail if you don't enclose the search term within double quotes.  

For example, a search for: Gfa_CB, returns nothing.  

If you enclose the word using double quotes as in: "Gfa_CB", this returns at least 2 posts *.

*(By the way, using single quotes as in: 'Gfa_CB' does not work either.)
