Sphinxsearch索引min_stemming_len

Question

这是我的sphinx搜索配置(sphinxsearch_0.9.9-6_amd64)：

index FULL
{
    charset_type            =       utf-8
    source                  =       FULL
    path                    =       /var/sphinx/data/Full
    docinfo                 =       extern
    mlock                   =       0
    min_stemming_len        =       1
    min_prefix_len          =       1
    min_word_len            =       1
    html_strip              =       1
    index_exact_words       =       1

}

searchd
{
    listen                  =       192.168.2.3
    log                     =       /var/log/sphinxsearch/searchd.log
    query_log               =       /var/log/sphinxsearch/query.log
    read_timeout            =       3
    client_timeout          =       60
    max_children            =       30
    pid_file                =       /var/run/searchd.pid
    max_matches             =       1000
    seamless_rotate         =       1
    preopen_indexes         =       0
    unlink_old              =       1
    mva_updates_pool        =       1M
    max_packet_size         =       8M
    max_filters             =       256
    max_filter_values       =       4096
}

我使用php作为客户端

$sphinx_client->SetServer('localhost', 9312);
$sphinx_client->SetConnectTimeout(1);
$sphinx_client->SetArrayResult(true);
$sphinx_client->setRankingMode(SPH_RANK_WORDCOUNT);
$sphinx_client->SetMatchMode(SPH_MATCH_EXTENDED2);
if ($mode == 'all') {
$sphinx_client->SetSortMode(SPH_SORT_RELEVANCE, 'category');
} else {
$sphinx_client->setFilter('category', array($this->_filter_category), FALSE);
}
$sphinx_client->SetLimits(0, $this->_limit);
$results = $sphinx_client->Query('"^'.$query.'$"', 'FULL');

例如，我在索引中有这些名字: 1. Alex 2. Alen 3. George 4. A 5. G

当我尝试搜索简单的1字符字符串"A“时，我得到Alen / Alex /A，依此类推。

如何根据字符串长度进行搜索，以便按正确的顺序显示它们，如:A/ Alen / Alex ...

我还得到“警告:索引'FULL'：无形态，index_exact_words=1没有效果，忽略”

诚挚的问候

使用序数字段( str2ordinal )，执行常规搜索，但修改排序模式:切换到扩展模式，并使用像$sphinx_client->SetSortMode(SPH_SORT_EXTENDED，'@weight desc，myordinal asc‘这样的组合；
