Thanks for this - its interesting how I have come to this conclusion as well.

My reworked approach is to return a list of results with a probability or certainty score.

In the situation of someone searching for London, I need to add some sort of priority for London, UK.

My dataset is sourced from an opensource JSON file which I am now pre-processing and identifying all collisions on it.

There are so many collisions!

Could I pick your brains and you could critique my approach? Thanks
