Also, what does the “prefix” actually do and how is it intended to be used?
BTW, similar problems is mentioned here Why is adding custom docs so hit or miss with Cursor?
I added same Angular docs link again and this time it has found 110 pages for What is Angular? • Angular compared with your 291 ones (not sure which URL you used though). Perhaps this is some kind of bug?
Edit: Home • Angular seems to redirect to What is Angular? • Angular BTW.
