There’s some wonkiness in the search function, in that it can’t deal with quotation marks, even if you include the quotation marks in your search.
Thus, if you’re searching thread titles to see if there’s something already started about a book, movie, or TV show, and the person who started that thread used quotation marks around that title – or even on one end of that title – the SDMB search will not find it.
*Can’t find: * Thread about “Name of Movie”
The Google search can cope; see the ATMB post on how to run a Google search.
If you’re starting a thread and want to be nice to people looking for it later, put spaces between the title and its quotes:
*Can find: * Thread about " Name of Movie "
