在1年查询中多次重复每周查询

我有一个查询，它给出了1周内'search_term'使用次数的结果。这是以下查询

SELECT search_term, COUNT(DISTINCT log_search.id) AS search_count, COUNT(DISTINCT log_search.user_id) AS unique_search_count 
FROM log_search 
LEFT JOIN log_session_start ON log_session_start.gg = log_search.gg
WHERE log_search.search_term = 'christmas' AND log_search.date_id >= 20140101 AND log_search.date_id <=20140131 AND log_session_start.site_id=1;

正如您所看到的，我使用log_search.date_id来指定一年中的给定周。现在我希望获得给定年份的所有周的结果，例如2014年。我可以在PHP中重复此查询52次，但这不是我想要的。我想要所以我在下一个查询时出现了。

FROM log_search 
LEFT JOIN log_session_start ON log_session_start.gg = log_search.gg
WHERE log_search.search_term = 'christmas' AND log_session_start.site_id=1;

这个查询的问题是它只给我'search_count'而不是'unique_search_count'。

我正在试图弄清楚如何在1次查询中重复第一次查询52次（比如第二次查询）。有人可以帮助我吗？

谢谢！

如果您对显示“search_results”而不是“unique_search_results”的第二个查询感到困扰，您可以运行添加了group by的查询。它会显示具有相同搜索结果的分组结果。我完全不了解您的查询，但如果您想要所有unique_search_results的计数，您可以使用group by
