Ruby on rails 思考斯芬克斯未知标识符groupby

根据文档，我尝试使用Thinking Sphinx搜索和group_by option：

但是这段代码生成了不正确的Sphinx查询

SELECT *, groupby() as sphinx_internal_group, count(*) as sphinx_internal_count 
FROM `point_core`, `point_delta` 
WHERE MATCH('point') AND `sphinx_deleted` = 0 
GROUP BY `tour_id` LIMIT 0, 20

这会引起错误：

ThinkingSphinx::ParseError: index point_core,point_delta: 
parse error: unknown identifier 'groupby' (not an attribute, not a function) - 
SELECT *, groupby() as sphinx_internal_group, count(*) as sphinx_internal_count 
FROM `point_core`, `point_delta` WHERE MATCH('point') AND `sphinx_deleted` = 0 
GROUP BY `tour_id` LIMIT 0, 20; SHOW META

我使用的是thinking-sphinx-3.1.1

按选项使用分组的正确方式是什么？

听起来您使用的是Sphinx 2.0.x-思考Sphinx v3.1.x默认情况下需要Sphinx 2.1.x。但您可以按照Sphinx2.0.x所期望的方式行事。

是的。旧斯芬克斯是邪恶的根源。我安装的Sphinx版本是Sphinx2.0.4，目前我已将其升级到2.1.9。所以，现在它的工作完美。谢谢你，帕特。
