Resource search remove auto-added http prefix (#334)

- remove previous optimization that auto-added 'https://' prefix to search
queries, which resulted in 'urn:' resources not being searchable.
also caused unintuitive behavior, where 'ht' would show no results while
'http' would, now fixed. Results in more predictable search results in
the end.
- Also default to contains instead of prefix search by default
