Fun idea. It seems to be getting stuck on the first word you enter.
e.g. you get the same results for “London” as you do for “London cats”, “London cat rescue” and “London test”.
The first thing I do to test a search engine is to search for my own username on various public sites to see if it can find me. It didn’t find me. But keep it up and I’m sure I’ll be in there eventually (or maybe a overestimate how interesting I am, hehe).
I get this is your usual testikg case for search engines, but if you've read their README you'd have seen its inaproppriate for the project at the current stage.
