示例1: getQuery

import org.apache.lucene.search.BooleanQuery; //导入方法依赖的package包/类
@Override
public Query getQuery(Element e) throws ParserException {
  BooleanQuery bq = new BooleanQuery(DOMUtils.getAttribute(e, "disableCoord", false));
  bq.setMinimumNumberShouldMatch(DOMUtils.getAttribute(e, "minimumNumberShouldMatch", 0));
  bq.setBoost(DOMUtils.getAttribute(e, "boost", 1.0f));

  NodeList nl = e.getChildNodes();
  for (int i = 0; i < nl.getLength(); i++) {
    Node node = nl.item(i);
    if (node.getNodeName().equals("Clause")) {
      Element clauseElem = (Element) node;
      BooleanClause.Occur occurs = getOccursValue(clauseElem);

      Element clauseQuery = DOMUtils.getFirstChildOrFail(clauseElem);
      Query q = factory.getQuery(clauseQuery);
      bq.add(new BooleanClause(q, occurs));
    }
  }

  return bq;
