sphinx 查询没找到索引的问题求大佬指点，提示 WARNING: No extra index definitions found in data folder

情况是这样的，我用 sphinx 创建了本地索引。

using config file 'D:\sphinx\bin\sphinx.conf'...
indexing index 'test1'...
collected 3547 docs, 2.9 MB

然后，启动 searchd

实际看到 data 目录下是有 test1 开头的多个文件的。
test1.sha
test1.spa
test1.spd
test1.spe
test1.sph
test1.spi
test1.spj
test1.spk
test1.spp

然后，sphinx.conf 文件是直接拿 etc 下的 mini 进行修改的。
