Boto AWS CloudSearch返回排名/分数

Question

我正在使用Boto的CloudSearch API来查询CloudSearch索引。我找不到检索每个搜索结果的排名/分数的方法。有可能吗？

Answer 1

将rank表达式的名称添加到return_fields参数：

import boto
conn = boto.connect_cloudsearch(key,secret)
domain = conn.create_domain('domain_name')
search_service = domain.get_search_service()

results = search_service.search(query, return_fields=['text_relevance','name_of_custom_rank_expression'])

for result in results:
    score = result['data']['name_of_custom_rank_expression'][0]
