I am trying to find RSS feeds that contain keywords in the URL. Here are some examples that us the keywords "blood test": https://news.google.com/news/feeds?hl=en&gl=us&q=blood%20test&um=1&ie=UTF-8&output=rss http://clinicaltrials.gov/ct2/results/rss.xml?rcv_d=&lup_d=14&term=blood+test&show_rss=Y&sel_rss=mod14&count=10000 http://olmis.org/olmis/rssjobfeed.xml?keyword=blood&keyword=test%0D%0A&area=000000 Might there be a method or "trick" to finding such RSS feeds? (not singular category or aggregator).
