Php 如何使用sphinx进行短语搜索

我需要使用sphinx创建短语搜索。我使用这个配置文件创建了索引

source sphinx_search
{
    type                                    = mysql
    # some straightforward parameters for SQL source types
    sql_host                                = localhost
    sql_user                                = root
    sql_pass                                = root
    sql_db                                  = mydatabase
    sql_port                                = 3306

    sql_query                       = \
        SELECT userId, usertype_id, searchdata from tbl_user;

    #sql_attr_uint                       = userId
    sql_attr_uint                       = usertype_id

     #document info query, ONLY for CLI search (ie. testing and debugging)
     #optional, default is empty
     #must contain $id macro and must fetch the document by that id
    sql_query_info      = SELECT * FROM tbl_user WHERE userId=$id;

}
index sphinx_search {
    source                          = sphinx_search
    path                            = /var/lib/sphinx/sphinx_search
    morphology                      = stem_en
    min_stemming_len        = 4
    stopwords                       = /var/data/sphinx/stopwords.txt
    min_word_len            = 3
    min_prefix_len          = 3
    min_infix_len           = 0
    enable_star                     = 1
    phrase_boundary = ., ?, !, U+2026 # horizontal ellipsis
    phrase_boundary_step = 100
    html_strip = 1

} 

indexer {
    mem_limit = 256M    
   #mem_limit       = 128M
    max_xmlpipe2_field = 16M 
}


searchd {   
    compat_sphinxql_magics  = 0     
    listen          = 9312  
    listen          = 9306:mysql41  
    log         = /var/log/sphinx/searchd.log   
    query_log       = /var/log/sphinx/query.log     
    read_timeout        = 5     
    max_children        = 30    
    pid_file        = /var/run/sphinx/searchd.pid   
    max_matches     = 10000     
    seamless_rotate     = 1     
    preopen_indexes     = 1     
    unlink_old      = 1     
    workers     = threads # for RT to work  
    binlog_path     = /var/data/ 
}

如果我试图寻找“水污染”这个词

搜索结果如下所示

words:
1. 'water': 10554 documents, 37143 hits
2. 'pollut': 1902 documents, 9657 hits

第一个问题是它没有完全使用“污染”这个词，而是使用了“污染”

第二个问题是它没有搜索完整的单词。即使我搜索

“水污染” 像这样

第三个问题，我无法使用userId对结果进行排序。如果我尝试添加

sql\u attr\u uint=userId

它的索引不正确

任何机构都可以帮助我解决这些问题。请帮助我。

简而言之，您必须设置扩展匹配模式并使用：

请注意搜索词周围的双引号。

请显示搜索请求的代码。

$cl->SetMatchMode ( SPH_MATCH_EXTENDED );
$cl->Query ( '"Water pollution"' );
