To search for a particular message, open Semaphor and navigate to the channel the message was sent from. Select the blue magnifying glass icon in the top right of the Semaphor application. Enter the text you are looking for, give it some time as if you have a very large team, it must parse through the entirety of your channel message history.
Once you no longer need to search, simply delete the text in the search box to return Semaphor to its normal view.
