The bleve path token filter added in
https://github.com/go-gitea/gitea/pull/32210 never generated the full
path of a file, so searching a file by its path (e.g. `potato/ham`)
found nothing. It also gave the path tokens made-up offsets instead of
their position in the path.
The filter is replaced by a tokenizer that emits the raw path suffixes
starting at each segment and word (`potato/ham.md`, `ham.md`). Paths
below the root now match too, as do names containing `-` or spaces and
dotfiles. An exact file name also ranks above files inside a directory
with the same name.
