Important update : It turns out that #Epicyon does support full text search of your own posts! I was just told that using an ' (apostrophe) right before the search string indicates a full text search.
A hidden gem or a not-so-well-documented feature in Epicyon. For example, if I want to find my posts that mention WordPress, I should enter 'WordPress in the search box. If I wish to find out my posts about "colours and composition", I should enter 'colours and composition.
