Best index structure for this case is suffix tree Lucene does not implements this type of index so its substring search is slow. But lucene has prefix tree index which mean you can do fast search if you search terms by their prefix.
WARNING: min_infix_len is not supported yet with dict=keywords; using dict=crc
我的最小配置文件：
source sour
{
type = xmlpipe2
xmlpipe_command = type C:\Temp\1\sphinx\input.xml
}
index inde
{
source = sour
path = testpa
enable_star = 1
dict = keywords
charset_type = utf-8
min_infix_len = 1
}
Sphinx does support effective substring searches since Version 2.0.1-beta, 22 apr 2011. Unfortunately as of today this support regards only beta versions, as mentioned here.
I made a try with 2.1.1 beta version. It seems to work correctly. See the manual entry for dictionary type, read about keywords type.
When I tried to use 2.0.6 release version, it fell back to inefficient crc index, giving the following warning during indexing:

这种情况下的最佳索引结构是 后缀树
Lucene 没有实现这种类型的索引，因此它的子字符串搜索速度很慢。但是 lucene 有前缀树索引，这意味着如果您通过前缀搜索术语，您可以进行快速搜索。

自 2011 年 4 月 22 日版本 2.0.1-beta 起，Sphinx 确实支持有效的子字符串搜索。不幸的是，截至今天，此支持仅考虑beta 版本，如此处所述。
我尝试了2.1.1 beta版本。它似乎工作正常。请参阅手动输入了解字典类型，了解
关键字< /代码> 类型。当我尝试使用 2.0.6 发行版时，它回退到低效的 crc 索引，在索引期间给出以下警告：
