示例1: getRangeQuery

import org.apache.lucene.queries.ChainedFilter; //导入依赖的package包/类
public Query getRangeQuery(QParser parser, SchemaField field, final CurrencyValue p1, final CurrencyValue p2, final boolean minInclusive, final boolean maxInclusive) {
  String currencyCode = (p1 != null) ? p1.getCurrencyCode() :
                        (p2 != null) ? p2.getCurrencyCode() : defaultCurrency;

  // ValueSourceRangeFilter doesn't check exists(), so we have to
  final Filter docsWithValues = new FieldValueFilter(getAmountField(field).getName());
  final Filter vsRangeFilter = new ValueSourceRangeFilter
    (new RawCurrencyValueSource(field, currencyCode, parser),
     p1 == null ? null : p1.getAmount() + "", 
     p2 == null ? null : p2.getAmount() + "",
     minInclusive, maxInclusive);
  final Filter docsInRange = new ChainedFilter
    (new Filter [] { docsWithValues, vsRangeFilter }, ChainedFilter.AND);

  return new SolrConstantScoreQuery(docsInRange);

示例2: chain

import org.apache.lucene.queries.ChainedFilter; //导入依赖的package包/类
/**
 * Returns all filters in a OR operation
 */
private static Filter chain(final int logic, Filter... filters) {
    filters = normalize(filters);

  } else {
    //NOTE By using the FieldCache we re-use a cache
    // which is nice but loading it in this way might be slower than say using an
    // intersects filter against the world bounds. So do we add a method to the
    // strategy, perhaps?  But the strategy can't cache it.
    docsWithField = FieldCache.DEFAULT.getDocsWithField(context.reader(), field);

    final int maxDoc = context.reader().maxDoc();
    if (docsWithField.length() != maxDoc )

      return null;//match nothing
    } else if (docsWithField instanceof Bits.MatchAllBits) {
      docsWithField = null;//all docs
    }

  //not so much a chain but a way to conveniently invert the Filter
  DocIdSet docIdSet = new ChainedFilter(new Filter[]{intersectsFilter}, ChainedFilter.ANDNOT).getDocIdSet(context, acceptDocs);
  return BitsFilteredDocIdSet.wrap(docIdSet, docsWithField);
