English Only?

[Fot3k]

Hi, is there any way to search and retweet results with English only?

I have lang: en defined in my config but some tweets have mixed English and none English in them so they still get through. Or even better use location to only search for tweets in certain countries. I understand these can only be found if the user/profile has defined their location but most businesses will have this set hence improve the quality of results and avoid so many fake giveaways.

Recent example:

*GIVE AWAY*
Dikarnakan tdk memungkinkan untuk GiveAway 1slice Red Velvet Pie dari Union, jadinya memutuskan untuk GA 100rb untuk 1orang.
caranya; Follow, Rep, Retweet. thats it

Diumumkan hari ini jam 23:00, dan pemenang dipilih secara acak, happy friday fellazz

Thanks.
