Can't use brackets in the URL

[jodinathan]

This works: http://localhost:8080/api/v1/webinar/list?map=%7B%22fields%22%3A%22id%22%2C%22filter%22%3A%7B%22title%22%3A%5B%22regex%22%2C%22title%22%5D%7D%2C%22link%22%3A%7B%22inner%22%3A%7B%7D%7D%7D

this doesn't: http://localhost:8080/api/v1/webinar/list?map={"fields":"id","filter":{"title":["regex","5802d1db2db83743e47f51a0"]},"link":{"inner":{}}}

edit to clarify: if I remove the [] from the second url, it works

I didn't even know this was such a thing. Oh well.
