rustdoc-search: count path edits with separate edit limit Avoids strange-looking results like this one, where the path component seems to be ignored:  Since the two are counted separately elsewhere, they should get their own limits, too. The biggest problem with combining them is that paths are loosely checked by not requiring every component to match, which means that if they are short and matched loosely, they can easily find "drunk typist" matches that make no sense, like this old result: std::collections::btree_map::itermut matching slice::itermut maxEditDistance = ("slice::itermut".length) / 3 = 14 / 3 = 4 editDistance("std", "slice") = 4 editDistance("itermut", "itermut") = 0 4 + 0 <= 4 PASS Of course, `slice::itermut` should not match stuff from btreemap. `slice` should not match `std`. The new result counts them separately: maxPathEditDistance = "slice".length / 3 = 5 / 3 = 1 maxEditDistance = "itermut".length / 3 = 7 / 3 = 2 editDistance("std", "slice") = 4 4 <= 1 FAIL Effectively, this makes path queries less "typo-resistant". It's not zero, but it means `vec` won't match the `v1` prelude. This commit also adds substring matching to paths. It's stricter than the substring matching in the main part, but loose enough that what I expect to match does. Queries without parent paths are unchanged. |
