Thanks for letting us know about this. I definitely see why this result is unwanted. Unfortunately, this is an example of the current search system working as intended: a query for data science on Persian Wikipedia is returning results that contain the English terms data and science -- note that searching for "data science" will not return the problematic example.
I will be working with the Search team to address the issue of problematic/undesirable search results more generally as we build out a Search team roadmap, so that we can address the issue more comprehensively in the future instead of trying to address individual edge cases, which is likely not scalable effort.
