len(pats) will throws IndexError. if using pats = Patent.objects.filter(title="tennis", issue_date="2010-01-01->2010-02-27")

I modified the example in https://patent-client.readthedocs.io/en/latest/index.html#super-quick-start

Patent.objects.filter(title="tennis", issue_date="2010-01-01->2010-12-31")`

to

pats = Patent.objects.filter(title="tennis", issue_date="2010-01-01->2010-02-27")

Then

len(pats) > 10 # throw error in  self.num_results = int(soup.find_all("i")[1].find_all("strong")[-1].text)

Thank you for your interest in Patent Client! I don't think this is an issue any longer. The Readme assigns the result to the pats variable. Let me know if this isn't right, and I'm happy to revisit.

Hi @parkerhancock ,

My previous description is not clear. I tried the same query condition on patft and there is only one search result. The special thing is that it will automatically redirect to the patent page. If using a python script to query, the result is a small html page contains single document this word and the patent URL listed inside but it is not the predicted result page. Therefore, it will throw an exception here

            self.num_results = int(soup.find_all("i")[1].find_all("strong")[-1].text)

I made some workaround code here which is not beautiful and just as a reference, grimmer0125@8943ca9#diff-b6dbafaca666db361cb7b2b2266719b822e2dcecd53671c5f29dcf92a6590799R158
