我应该让所有用户的国籍代码等于“ MD”或“ GB”或“ IT”
应该类似于mysql中的此查询:
(@nationality_code ("^MD$" | "^GB$" | "^IT$"))
更新 如果仅搜索MD和GB,则会收到正确的结果:
我执行的查询是这样:
SELECT * FROM users WHERE nationality_code IN ('MD', 'GB', 'IT')
但是,如果我还添加“ ^ IT $”,就不会再有“ MD”国籍的用户了。
如果删除开始/结束修饰符,则会收到预期的结果,为什么会出现这种情况?
更新 因此,这里是我的索引转储和sphinx.conf文件:sphinx-dump
答案 0 :(得分:1)
是的。这个表达是正确的。对我来说很好:
List
确保索引中确实只有MD / GB / IT,之前/之后没有任何内容,并且没有min_word_len <2。
答案 1 :(得分:0)
There's a problem with Sphinx 3.0.3 ver, because with Sphinx 2.2.11 it works
