I use Twitter Streaming API (filter endpoint) to get tweets filtered by tracks in russian language.
After some analysis I found that I cannot get tweets with words preceded or followed by dots, commas, etc.
Example: tweet with ‘кот’ (cat in russian) will be streamed, but I cannot get the tweet with ‘кот,’.
At current state API provides incomplete data.
May be this “bug” had been already scheduled for investigation.
Please, advice any workarounds for this problem.
