Sphinxql - 如何在不使用sphinxapi.php的情况下在PHP中使用Sphinxql时使用具有顺序的查询

Question

我一直在使用mysql FTS,但最近切换到sphinx进行测试.

在centos 7上安装了sphinx

Linux production 3.10.0-123.8.1.el7.x86_64 #1 GNU/Linux

的sphinx.conf

source content_src1
{
    type            = mysql
    sql_host        = localhost
    sql_user        = 
    sql_pass        = 
    sql_db          = t_prod2
    sql_port        = 3306  # optional, default is 3306

    sql_query       = \
        SELECT content.record_num, \
                    content.title, \
                    content.category, \
                    content.upload_date, \
                    content.comments_count, \
                    content.verified, \
                    content.uploader, \
                    content.size \
                    FROM content WHERE enabled = 1 

    sql_attr_uint       = record_num
    sql_attr_string = title
}


index content_index1
{
    source          = content_src1
    path            = /var/lib/sphinx/content_index1
    morphology              = stem_en

    min_word_len            = 1
    min_prefix_len          = 0
    min_infix_len           = 1
    docinfo                 = extern 

}

我正在使用php连接sphinxql并运行查询,像这样

$sphinxql = @mysqli_connect($sphinxql_host.':'.$sphinxql_port,'','');

$sphinxql_query = "SELECT id FROM $sphinx_index WHERE MATCH('".mysqli_real_escape_string($prod1,$q)."') LIMIT  $from,$max_results";

简单查询工作正常,即没有条件顺序的查询.但是当我试图运行具有order by的sql查询时,sphinx会抛出错误.

即查询及其错误.

SELECT id FROM $sphinx_index WHERE MATCH('".mysqli_real_escape_string($prod1,$q)."') ORDER BY title DESC LIMIT  $from,$max_results

index content_index1: sort-by attribute 'title' not found

另一次尝试,我用@field名称替换了字段名称

SELECT id FROM $sphinx_index WHERE MATCH('".mysqli_real_escape_string($prod1,$q)."') ORDER BY @title DESC LIMIT  $from,$max_results

sphinxql: syntax error, unexpected USERVAR, expecting IDENT (or 55 other tokens) near '@title DESC LIMIT 0,25'

表格按标题,类别,upload_date,大小,已验证等字段排序

那么如何在我的sphinxql查询中使用order by

更新1

我已设法运行查询"没有按顺序",但查询"order by"工作不正常,不会给出错误,给出结果集,但如果我改变按属性排序的方向,结果集不会改变.

更新的字段和属性为.

sql_field_string = title
sql_field_string = og_name
sql_field_string = hash
sql_field_string = keywords

sql_attr_timestamp = upload_date_timestamp

sql_attr_uint = category
sql_attr_uint = comments_count
sql_attr_bool = verified
sql_attr_bigint = size

您是否尝试过将该列用作 sql_attr_string ？

http://sphinxsearch.com/docs/current.html#conf-sql-attr-string

您至少需要版本 2.0.1 才能在此类属性上使用 ORDER BY 子句：

从 2.0.1-beta 开始，字符串属性可用于排序和分组（ORDER BY、GROUP BY、WITHIN GROUP ORDER BY）。
