Codex search results treats Swedish diacritics as ascii equivalents when sorting results

Overview: When conducting title level searches in Codex for titles containing Swedish diacritics (å,ä,ö) the sort functionality behaves as if those characters are reduced to their ASCII equivalents (a,o).

Steps to Reproduce:

• Create a couple of records in Inventory with titles starting on a, å, ä or similar
  For example:
  "Den aktansvärda"
  "Den äkta varan"
  "Den åländska skärgården"

• Go to Codex and conduct a title search for Den
• Sort by title ascending order (arrow pointing up)

Expected Results:
Results are returned alphabetically (Swedish):
"Den aktansvärda"
"Den åländska skärgården"
"Den äkta varan"

Actual Results:
Results are sorted according to the attached image:
"Den aktansvärda"
"Den äkta varan"
"Den åländska skärgården"

Additional Information: Will add these in separate issues.

Note:
This particular issue might get solved by changing Collation on relevant tables in Postgres to Swedish (see https://www.postgresql.org/docs/9.1/static/collation.html), but I believe that this issue is related to a bigger discussions on search technology
