* removed 100 limit on file search results because we
load all results anyway
* expensive processing (parsing match content, utf encoding)
is done only for selected page in paginated output
'/-/' delimiter is used only in UI, in API we don't use it for
other endpoints. To align search endpoints with the rest of API
endpoints, this patch makes '/-/' optional for existing endpoints (to
keep backward compatibility).
Documentation is updated to prefer paths without '/-/'.
