User search not returning any results


#1

When I do a people search on the https://twitter.com/search for a particular user, it works (I get results):
https://twitter.com/search?q=from%3Ajennafischer

But when I do an api search for the exact same person using the exact same query, it doesn’t (I get no results):
https://api.twitter.com/1.1/search/tweets.json?count=10&q=from%3Ajennafischer&oauth

Why do these two things return different results? Why don’t I get results in my api query?
