There is a problem with the "Search This Blog" feature (Blogger calls them "gadgets") on this website (immediately to the right). The search does not work for the Brouwer Genealogy blog site itself, although it still does pick up searches from linked websites. Apparently this problem is occurring with other blogs created by Blogger as evident from this blog I found when searching on Google Web for answers to this problem (see the March 5, 2013 entry here).
Hopefully, someone with the power, will have realized this and it will be fixed. I, for one, used the Search This Blog feature a lot. If anyone has any insight into this issue, I (and I'm sure others) would be like to be informed. In the meantime, sorry for the inconvenience.
