我目前正在研究如何将 sphinx 集成到现有网站上。

我正在为一个出租度假屋的客户工作。他们有一个网站，客户可以在线预订。在他们的首页上，他们有一个搜索引擎，可以搜索他们所有的家（20k）并在各个领域对他们进行排序。过去，我们对每次搜索都进行 MySQL 查询。现在数据库已经增长了分配，这使得查询的允许速度比过去慢。出于这个原因，我们正在研究如何改进搜索引擎。我目前正在与 sphinx 合作，看看它是否适合我们。

我安装了 Sphinx 并具有以下源和索引：

  type = mysql
  sql_host = localhost
  sql_user = user

   sql_query= SELECT a.huis_id as huis_id, a.huis_code as huis_code, a.land_code,    a.regi_code, a.huis_naam, a.huis_plaats,a.multimedia,a.foto_a, a.foto_w,a.foto_a_full, a.foto_w_full, a.huis_van, a.huis_tm, a.hd, a.a_hd, st,a.sl, a.beds, a.bathr, a.baths,a.airport, a.huis_enqe_vr13_aantal, a.huis_enqe_vr13_punten, a.huis_longitude, a.huis_latitude, a.huis_catering_verplicht, 1w_min, 1w_max, 2w_min, 2w_max, 3w_min, 3w_max, wk_min, wk_max, lw_min, lw_max, mw_min, mw_max, age,(CASE WHEN vz200p239 = '1' or vz238 = '1' or vz235 = '1' THEN 1 ELSE 0 END) as relax,ph.plaatsnaam as hplaats,ph.hplaatsid,ps.subplaatsid,ps.plaatsnaam as splaats,ty20,ty30,ty40,ty50,ty60,ty70,ty90,ty160,becdir,huis_hbes_small, a.regi_oms_nl as regi_oms \

索引创建良好：

但是当我执行 SELECT * FROM huisjesIndex 时，我得到一个空集，但应该有超过 17k 条记录。难道我做错了什么？

我没有仔细检查，但看起来你已经将 sql_query 中的所有列定义为Attributes。

斯芬克斯不喜欢那样。它是一个文本搜索引擎，因此它需要一些全文Fields。

一个简单的解决方案（如果您确实想要所有这些属性）是使用 sql_field_string 使您的至少一个列成为字段和属性。

另一个 odity，但很可能仍然有效，是您使用 a.huis_id 作为 document_id，但将 a.huis_code 分组。如果它们不是 1:1 映射（并且是唯一的），那么您将遇到问题。我认为按document_id分组更常见。
