Add more search engines to supplement the cap of 100 results from itunes.
APIs for alternative search engines are mentioned in this post http://stackoverflow.com/questions/3201052/podcast-search-api - some appear to allow up 1000 queries in a day per user. This would be much more useful in finding long tail podcasts in certain niches. iTunes always returns the same results and the limit of 100 is frustrating.
I’m adding the 100 episodes limits when calling iTunes search APi. This is a good balance between performance, data usage and results
