Bug with non-ascii characters, quotes and OR operator in search? There seems to be a bug when I combine non-ascii characters, quotes and the OR operator when searching. 

All of these queries work ok: 


"pølser"
"pålegg"
pølser OR pålegg
"egg" OR "spekemat"


but


"pølser" OR "pålegg" 


always returns no result. 

The search form uses roughly this code: 

{% set searchTerm = craft.request.getParam('search') %}

{% set entries = craft.entries %}

... entries is optionally limited to a single section here, but it makes no difference here ... 

{% set entries = entries.search(searchTerm) %}


Any ideas? 

Cheers!

(edit to add code sample)
This looks like a bug to me too. Here are the search terms and generated queries:

'pølser OR pålegg' -
   SELECT * FROM `craft_searchindex` WHERE (MATCH(`keywords`) AGAINST('pølser palegg' IN BOOLEAN MODE)) AND `elementId` IN (3,18,21,22,23,24)

'"pølser" OR "pålegg"' -
   SELECT * FROM `craft_searchindex` WHERE (`keywords` LIKE '% pølser or %') AND MATCH(`keywords`) AGAINST('+palegg' IN BOOLEAN MODE) AND `elementId` IN (3,18,21,22,23,24)

'"egg" OR "spekemat"' -
   SELECT * FROM `craft_searchindex` WHERE ((`keywords` LIKE '% egg %') OR MATCH(`keywords`) AGAINST('spekemat' IN BOOLEAN MODE)) AND `elementId` IN (3,18,21,22,23,24)
