public SpanQParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest req) {
    super(qstr, localParams, params, req);
    IndexSchema schema = req.getSchema();

    //now set the params
    SolrParams comboParams = SolrParams.wrapDefaults(localParams, params);

    //preamble to initializing the parser
    Analyzer analyzer = schema.getQueryAnalyzer(); //default analyzer?

    defaultFieldName = getParam(CommonParams.DF);

    if (defaultFieldName != null) {
        SchemaField sf = schema.getField(defaultFieldName);
        if (sf != null && sf.getType() != null) {
            analyzer = sf.getType().getQueryAnalyzer();
        }/*from  w w w.j  a v  a 2s. c  o m*/
    }

    //initialize the parser
    parser = new SolrSpanQueryParser(defaultFieldName, analyzer, schema, this);

    parser.setAllowLeadingWildcard(comboParams.getBool(ALLOW_LEADING_WILDCARD, true));

    parser.setAutoGeneratePhraseQueries(comboParams.getBool(AUTO_GENERATE_PHRASE, false));

    }

    parser.setDefaultOperator(defaultOp);
