real-time - 实时索引上的 Sphinx 通配符匹配

Question

我创建了实时索引：

index berni_filter2
{
    rt_mem_limit    = 512M
    type            = rt
    path            = /var/lib/sphinxsearch/data/berni_filter

    rt_attr_uint    = product_id
    rt_attr_uint    = store_id
    rt_field        = product_name
    rt_attr_json    = attributes

    prefix_fields   = product_name
    expand_keywords = 1
    min_infix_len   = 2
    dict            = keywords
}

然后我尝试通过 SphinxQL 按产品名称字段获取数据：

SELECT product_id FROM berni_filter2 WHERE store_id = 0 AND MATCH ('@product_name mothercare')

此查询工作正常，但我需要找到部分单词，例如“mother”必须返回带有“mothercare”的产品。我试过了：

SELECT product_id FROM berni_filter2 WHERE store_id = 0 AND MATCH ('@product_name mother')
SELECT product_id FROM berni_filter2 WHERE store_id = 0 AND MATCH ('@product_name mother*')
SELECT product_id FROM berni_filter2 WHERE store_id = 0 AND MATCH ('@product_name *mother*')

我尝试将 min_infix_len 更改为 min_prefix_len。没有任何工作。

Answer 1

我的错误是，我没有从文件系统中删除数据文件，当更改配置时，这是最终的工作配置：

index berni_filter
{
    rt_mem_limit    = 512M
    type            = rt
    path            = /var/lib/sphinxsearch/data/berni_filter

    rt_attr_uint    = product_id
    rt_attr_uint    = store_id
    rt_field        = product_name
    rt_attr_json    = attributes

    index_exact_words = 1
    expand_keywords   = 1
    min_prefix_len    = 3
    min_word_len      = 2

    morphology        = stem_enru
    dict              = keywords
}

我遇到了同样的问题。删除索引文件对我也有帮助。在删除之前，我停止了 searchd 服务，然后重新启动它。
