Search on Mercury provided by ApacheSolr and hosted in tomcat. Tomcat is running on port 80. When a request contains UTF-8 characters there are percent encoding and Tomcat can't deal with it by default. See : http://wiki.apache.org/solr/SolrTomcat#URI_Charset_Config
Quote :
If you are going to query Solr using international characters (>127) using HTTP-GET, you must configure Tomcat to conform to the URI standard by accepting percent-encoded UTF-8.
Edit Tomcat's conf/server.xml and add the following attribute to the correct Connector element: URIEncoding="UTF-8".
<Server ...>
<Service ...>
<Connector ... URIEncoding="UTF-8"/>
...
</Connector>
</Service>
</Server>This is only an issue when sending non-ascii characters in a query request... no configuration is needed for Solr/Tomcat to return non-ascii chars in a response, or accept non-ascii chars in an HTTP-POST body.
Following the above advice, the ApacheSolr search works ok for non-English words, like for CJK and others. I thought to share this here since this might be an issue for others as well with multilingual sites or non English user content.

Thanks for the tip - we're going to do some testing and add it to Pantheon (Also added it to the documentation of this project).

Do note that it's also important to remove useBodyEncodingForURI from that Connector. I updated the documentation on troubleshooting Solr to reflect this.
Thx
