I am working on a project that requires me to filter out news story using story text. For example, I want the same results as the query R:8031.T NOT "mitsui" NOT "company limited" AND Language:LEN returns on EIKON new Monitor. How can i reproduce it in EIKON API for Python? Also, note that i am using "filter by headline and story text" in the EIKON app. Is there a way to do the same in API?
