Description

The SolrJ query operation fails to set the character encoding when doing a GET. It works when doing a POST.

The problem is that URLs are urlencoded with UTF-8 but the Content-type: header is not set. I tested it with "Content-Type:text/plain;charset=utf-8" and that worked. The Content-type header encoding defaults to ISO 8859-1.

The result is that SolrJ queries fail for any search with a character above 127. The work around is to use a POST query instead of a GET. I have not searched for other places. So, change:

QueryResponse qr = CommonsHttpSolrServer.query(query);

to:

QueryResponse qr = CommonsHttpSolrServer.query(query, SolrRequest.METHOD.POST);

One quirk of this behavior is that url-bashing a query string with an ISO 8859-1 character (like an umlaut) works in a browser, but fails in a SolrJ request.. It also searches correctly from the admin/index.jsp and admin/form.jsp pages, because they set the content-type in the FORM declaration.
