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;
}
