This should also be at the Right-Side of this BLOG. Note that this does not search the 'Labels'... so if the word appears only in the 'Labels' it will not show up in the search. To search 'Labels', use 'Find This Page' (see next point).
• Find This Page ~ (via 'Ctrl+F' or via 'Edit>Find This Page')
This searches this page only. Example, searching for 'bejewel' will still find 'bejeweled' in the LABELS list. Also very useful for searching the Labels.
.• Advanced Blog Search
by Google's BlogSearch (from the 2 links shown just below here)
Best used with advance search and remember to fill in the 'Blog URL' box for the Blog that you want to search. Very useful coz it offers suggestions. Example, while searching for 'bejewel', it will still suggest 'bejeweled' if bejewel is nowhere else on the Blog. There's a slight difference between the 2 links above, so slight, I can't tell the difference.
