Why do people choose such names for their product? It's s city and its one of the most widely reported works in education (programme for international student assessment) with millions of news articles. How do you want to be findable with a name like this?
We rely on different user intents. Search for "PISA engine" or "PISA search" and you will find this tool and not the city. Being found by the keyword `PISA` on Google is not necessarily our main goal.
We are not selling anything, the community is just building a product for IR research. We are willing to gain interest from skilled people in the end.
I don't think it really matters if there are `news` about the city, we are not targeting the news anyway.
Also, think about `Windows` or `Go`, there is no way you get confused once these words are in the right context.
While poor search recall is a bit ironic for the name of a search engine, I guess it's because Antonio has studied at the University of Pisa and later worked as researcher for the CNR institute for research, again in Pisa. (Me too, hi!).
