狮身人面像搜索:charset表困难

标签: php utf-8 sphinx character

我现在已经失去了两天的思绪......

我想在狮身人面像搜索中使用斯洛文尼亚字母,所有英文字母+čžš(以及以防万一)

我正在网上寻找合适的字符,但我发现蹲下......

所以我决定自己一步一步......

这是我的索引

index classifieds
{
    source          = classifieds_src
    path            = c:\Sphinx\data\classifieds
    docinfo         = extern

    min_infix_len       = 2
    infix_fields        = title,keywords,summary,text
    expand_keywords     = 1
    enable_star     = 1


    charset_type        = utf-8
    charset_table = 0..9, a..z, _, A..Z->a..z,-, U+002C, \
    U+010C->U+010D, U+0106->U+0107, U+0160->U+0161, U+017D->U+017E, \
    U+010D->c,U+0107->c, U+0161->s, U+017E->z, \
    U+010D, U+0107, U+0161, U+017E
}

我将大Č,ĆŠŽ映射到他们的小写对应物,并添加了映射 č进入c,ć进入c,š进入s和ž进入z 最后我将这四个字符添加到表格中....

这些是我的分类标题:

t1:HPUSBoptičnamiškazaprenosnik RH304 t2:ČiškaPCplusMO-U033 + F2(optična,brezžična,PS / 2) t3:MiškaLogitechoptičnaNanoM235 siva

db encoding:utf8_general_ci table的编码:utf8_general_ci 标题字段编码:utf8_general_ci

测试用例:

$testcase = array(
        "miška",
        "mi*ka",
        "Čiška",
        "čiška",
        "miska",
        "usb prenosnik",
        "prenosnik miska",
        "miška usb"
);

//api settings:

$this->sphinx->SetArrayResult(true);
$this->sphinx->setLimits(0, 100);
$this->sphinx->setMatchMode(SPH_MATCH_EXTENDED2);
$this->sphinx->SetSortMode(SPH_SORT_RELEVANCE, '@weight DESC');
$this->sphinx->SetRankingMode(SPH_RANK_PROXIMITY_BM25);
$this->sphinx->SetFieldWeights(array("title"=>100, "keywords"=>80, "summary"=>60,
"text"=>20, "slug"=>10));

最后是测试结果:

你可以清楚地看到我只在没有斯洛文尼亚特殊字符的查询中得到肯定的结果

请帮助我在这个

问题是sphinx索引器默认情况下不使用utf8字符集。修复了将以下内容添加到sphinx.conf

sql_query_pre = SET CHARACTER_SET_RESULTS=utf8
sql_query_pre = SET NAMES utf8

答案 1 :(得分:0)

在这里你可以找到许多不同的字符集表,也许其中一个适合你的语言:http://sphinxsearch.com/wiki/doku.php?id=charset_tables

答案 2 :(得分:0)

您应该设置一些参数。它们是ngram_len和ngram_chars。

首先,我遇到了同样的问题。然后我读了一本书使用sphinx 进行搜索的介绍,我发现默认的charset和ngram_chars仅用于英语和俄语。所以你必须自己添加。

就我而言,我为中国人做了这些改变:

charset_table = U+FF10..U+FF19->0..9, 0..9, U+FF41..U+FF5A->a..z, U+FF21..U+FF3A->a..z,\
