org.apache.lucene.queryparser.xml.QueryTemplateManager
Provides utilities for turning query form input (such as from a web page or Swing gui) into Lucene XML queries by using XSL templates. This approach offers a convenient way of externalizing and changing how user input is turned into Lucene queries. Database applications often adopt similar practices by externalizing SQL in template files that can be easily changed/optimized by a DBA. The static methods can be used on their own or by creating an instance of this class you can store and re-use compiled stylesheets for fast use (e.g. in a server environment)

      String xslFile = config.getInitParameter("xslFile");
      String defaultStandardQueryParserField = config.getInitParameter("defaultStandardQueryParserField");




      //Load and cache choice of XSL query template using QueryTemplateManager
      queryTemplateManager = new QueryTemplateManager(
          getServletContext().getResourceAsStream("/WEB-INF/" + xslFile));


      //initialize an XML Query Parser for use by all threads
      xmlParser = new CorePlusExtensionsParser(defaultStandardQueryParserField, analyzer);
    } catch (Exception e) {
