Issue & forks search is not effective

Parsing net graph might worth a try.
More importantly, issue search finds totally unrelated matches sometimes:

//github.com/gregmuellegger/django-mobile/issues/3
//github.com/svetlyak40wt/django-fields/issues/3

And a big miss here:

//github.com/jezdez/django_compressor/

Possible solutions:
- query "python 3 support"
- use search api instead of legacy api?
