Looking at Stackexchange most of the sites have less than a million (possible?) queries(questions). Stackoverflow, probably the largest, has 18 million questions. Wikipedia article count is about 5 million.
Is the assumption that people are coming up with 1000 different ways to query every possible result endpoint?
The number 4 billion is made-up. It was chosen in order to illustrate the scale of the problem we are trying to solve. And it also happens to be just below the maximum number possible to store in an unsigned 4 byte integer. This is of course beneficial when trying to build an index with a small footprint. With more queries, we would have to consider using long integers (8 bytes) or some custom type with e.g. 5 bytes.
If you're interested in where the queries come from, you might find these previous posts interesting: https://0x65.dev/blog/2019-12-05/a-new-search-engine.html https://0x65.dev/blog/2019-12-06/building-a-search-engine-fr...
Thanks for the posts, they’re fascinating and the idea of more alternative search engines would be great. Best of luck!
