Sphinx delta索引忽略主索引

我有一个非常奇怪的问题，由于某种原因，我的索引根本没有正常工作。

我已经在Sphinx中建立了一个完全工作的增量索引，并带有完整的cron作业，以保持它的形状和一切都很好。

然后我来用PHP查询:

class sphinx_searcher{
function __construct(){
    $config = array('host'=>'localhost', 'port'=>9312);
    $this->sphinx = new SphinxClient();
    $this->sphinx->SetServer ( $config['host'], $config['port'] );
    $this->sphinx->SetConnectTimeout ( 1 );
}
function query(){
    $this->sphinx->SetSortMode(SPH_SORT_RELEVANCE);
    $this->sphinx->SetLimits(0, 20); // Testing first page
    $this->sphinx->SetRankingMode(SPH_RANK_PROXIMITY_BM25);
    $this->sphinx->SetArrayResult ( true );
    $res = $this->sphinx->Query("040*", "media media_delta");
    if($res)
        return $res;
    else
        return $this->sphinx->GetLastError();
}
}

由于某种原因，它取其中一个索引(目前只取后者)。

当我单独查询媒体时，我得到doc id 1和2，但当我同时查询时，我只得到doc id 3，这是在增量索引中。

这是我的数据源配置:

source media
{
type            = mysql
sql_query_pre       = SET NAMES utf8
sql_query_pre = REPLACE INTO sph_counter SELECT 1, MAX(id) FROM documents
sql_query = '
    SELECT id, deleted, _id, uid, listing, title, description, tags, author_name, playlist, UNIX_TIMESTAMP(date_uploaded) AS date_uploaded '
    FROM documents '
    WHERE id<=( SELECT max_doc_id FROM sph_counter WHERE counter_id=1 )
sql_field_string = tags
sql_field_string = description
sql_field_string = author_name
sql_field_string = title
sql_attr_uint = deleted
sql_attr_string = _id
sql_attr_string = uid
sql_attr_string = listing
sql_attr_uint = playlist
sql_attr_timestamp = date_uploaded
sql_ranged_throttle = 0
sql_query_info = SELECT * FROM media WHERE id=$id
sql_query_killlist = SELECT id FROM documents WHERE deleted = 0
}

source media_delta : media
{
sql_query_pre = SET NAMES utf8
sql_query = '
    SELECT id, deleted,  _id, uid, listing, title, description, tags, author_name, playlist, UNIX_TIMESTAMP(date_uploaded) AS date_uploaded '
    FROM documents '
    WHERE id>( SELECT max_doc_id FROM sph_counter WHERE counter_id=1 )
}

这是我的索引配置:

index media
{
source          = media
path            = /home/sam/sphinx/var/data/media
docinfo         = extern
mlock           = 0
morphology      = stem_en, stem_ru, soundex
min_word_len        = 1
charset_type        = sbcs
min_infix_len       = 2
infix_fields        = title, tags 
enable_star     = 1
expand_keywords     = 1
html_strip      = 0
index_exact_words   = 1
}
index media_delta : media
{
source = media_delta
path = /home/sam/sphinx/var/data/media_delta
}

我真的很困惑，我有什么错了，希望有人在这里可以帮助我找出什么是错的?

不再使用所有索引:

array(9) { ["error"]=> string(0) "" ["warning"]=> string(0) "" ["status"]=> int(0) ["fields"]=> array(4) { [0]=> string(5) "title" [1]=> string(11) "description" [2]=> string(4) "tags" [3]=> string(11) "author_name" } ["attrs"]=> array(10) { ["deleted"]=> int(1) ["_id"]=> int(7) ["uid"]=> int(7) ["listing"]=> int(7) ["title"]=> int(7) ["description"]=> int(7) ["tags"]=> int(7) ["author_name"]=> int(7) ["playlist"]=> int(1) ["date_uploaded"]=> int(2) } ["total"]=> string(1) "0" ["total_found"]=> string(1) "0" ["time"]=> string(5) "0.000" ["words"]=> array(1) { ["040*"]=> array(2) { ["docs"]=> string(1) "2" ["hits"]=> string(1) "2" } } } 

谢谢,
