Hi Vishal and thank you for your answer.
The problem is base code and language id is correct. The problem is a little bit interesting let me explain if I can, and will send you logs if able to get them. I am using TargetingIdeaService stats not ideas...
If you select a Turkish word and make the language id 1037 it returns with NULL values but if you disable language selector it returns 0 as values. There are several thing I've mentioned like if the word is homonymous with another language word it fails... Why should I select the right language for word to make it work properly, it can just return 0 if there are no results. I can give samples like this as: "bol", "cep", "nice (not the English one :P)", etc.
Thank you for your time.
