Description

I run email connector job and follow "Simple History" from UI. I see an error as follow:

Error from server at http://localhost:8983/solr/mycore: non ok status: 414, message:Request-URI Too Long

It is sent by Solr.

Solr logs say:

HttpParser - URI is too large >8192

and

HttpParser - bad HTTP parsed: 414 for HttpChannelOverHttp@2b6931dd{r=0,​c=false,​a=IDLE,​uri=null} 

ManifoldCF ModifiedHttpSolrClient.java has following code:

 // It is has one stream, it is the post body, put the params in the URL
      else {
        String pstr = toQueryString(wparams, false);
        HttpEntityEnclosingRequestBase postOrPut = SolrRequest.METHOD.POST == request.getMethod() ?
            new HttpPost(url + pstr) : new HttpPut(url + pstr);

There is "pstr" field appended to the URL. "pstr" field have all Solr params. It contains email content. We have "URI is too large" error when email has large content.
