   Format: MarkdownItexToday I was trying to find an nLab article on $L^p$ spaces, and tried doing a search on "L^p space", which came up empty. (I didn't think to try "L-p space", and I didn't remember it was called [[Lebesgue space]].) So I tried to edit in a redirect to L^p space at [[Lebesgue space]], but I don't think it worked. I hope I didn't inadvertently mess anything up as a result. I figure that carets cause a hiccup for page names.

   Format: MarkdownItexThe problem is in the search, not the page. The internal search uses regular expressions and `^` is a special character that matches the start of a line. In some regular expressions then it reverts to matching just `^` when used in the middle of a pattern, but clearly this isn't the case here. So `L^p space` is looking to match: ~~~ L p space ~~~ The way to get round this is to escape the `^`: if you search for `L\^p space` then you get taken straight to [[L^p space]] (as it's the only match; all the other pages have `$L^p$ space`).
