示例1: rewrite

import org.apache.lucene.index.IndexReader; //导入方法依赖的package包/类
@Override
public Query rewrite(IndexReader reader) throws IOException {
    if (getBoost() != 1.0F) {
        return super.rewrite(reader);
    }
    if (reader instanceof DirectoryReader) {
        String joinField = ParentFieldMapper.joinField(parentType);
        IndexSearcher indexSearcher = new IndexSearcher(reader);
        indexSearcher.setQueryCache(null);
        indexSearcher.setSimilarity(similarity);
        IndexParentChildFieldData indexParentChildFieldData = parentChildIndexFieldData.loadGlobal((DirectoryReader) reader);
        MultiDocValues.OrdinalMap ordinalMap = ParentChildIndexFieldData.getOrdinalMap(indexParentChildFieldData, parentType);
        return JoinUtil.createJoinQuery(joinField, innerQuery, toQuery, indexSearcher, scoreMode, ordinalMap, minChildren, maxChildren);
    } else {
        if (reader.leaves().isEmpty() && reader.numDocs() == 0) {
            // asserting reader passes down a MultiReader during rewrite which makes this
            // blow up since for this query to work we have to have a DirectoryReader otherwise
            // we can't load global ordinals - for this to work we simply check if the reader has no leaves
            // and rewrite to match nothing
            return new MatchNoDocsQuery();
        }
        throw new IllegalStateException("can't load global ordinals for reader of type: " + reader.getClass() + " must be a DirectoryReader");
    }
