Improve QueryElevationComponent to Query Complex Strings
--------------------------------------------------------

                 Key: SOLR-1418
                 URL: https://issues.apache.org/jira/browse/SOLR-1418
             Project: Solr
          Issue Type: Improvement
    Affects Versions: 1.4
         Environment: windows xp/jdk1.6/tomcat6
            Reporter: tom liu


In Solr 1.4, QueryElevationComponent use Query DocNode to create ElevationObj, then add to elevationCache. After that, when user invoke a querystring qstr, prepare method invokes getAnalyzedQuery(qstr) to get analyzedQueryStrings, then get ElevationObj from elevationCache.
So, user input string qstr must be Query-DocNode-String, if not , we will not get Elevation results from elevation.xml.

I think this would be improved. Such as:
1. Change method [String getAnalyzedQuery( String query ) throws IOException] to [String[ ] getAnalyzedQuery( String query ) throws IOException]
2. Change method prepare:
booster = getElevationMap( reader, req.getCore() ).get( qstr );
to:
for(String qstr : qstrs){
     booster = getElevationMap( reader, req.getCore() ).get( qstr );
     if(null != booster) break;
}
