I have developed a WordPress site for a client that has blog posts related to the stock market. My client wants to be able to search for stock tickers in the search field. I have added a tags search via a plugin called "Search Everything" so tags can be searched. The problem we have encountered is that some stock tickers are only a single letter (like "A") which then results in a very wide search and is not helpful. I'm either looking for a plugin that would allow for us to search something with a hash mark (#) next to it, (but then we would need to be able to add a hash to a tag). Or I am open to another suggestion, perhaps a custom category for stock ticker that could then have a custom search field. I am using the Genesis child theme Executive.
