Searching for individual episodes of podcasts

Is there any functionality to search for individual episodes within a podcast or feed? Some of the podcasts that I have been adding have a long history, and if I want to listen to anything old, the only way that I have been able to find was to expand the amount of episodes available so that it shows all of the episodes, and then choosing from there, but I could see that using up a lot of space. My wife uses a different Podcast app on her Galaxy but has been having a lot of issues with bluetooth connectivity. I wanted to reccommend Doggcatcher to her, but without the ability to search for individual episodes, it is a non starter. Thanks.
