举例

def query(dirName, key,pageLen,pageNum):
    ix = open_dir(dirName)
    with ix.searcher() as searcher:
        parser = QueryParser("title", ix.schema)
        myquery = parser.parse(key)
        print myquery

        results = searcher.search_page(myquery, int(pageNum), pagelen=pageLen)

        output = []
        for item in results:
            output.append(item.fields())

        return {'pageTotal':results.pagecount,
                'pageNum':results.pagenum,
                'pageLen':results.pagelen,
                'total': results.total,
                'ids': output}

results = query(dirName="indexdir", key='document OR path:/c',pageLen=1,pageNum=2)

1. 组合条件
2. 分页
3. 排序
