带有PHP的Spinx地理距离不会返回结果

我是Sphinx搜索的新手。我阅读了手册以及关于如何让Geodist工作并且没有结果的几个方法。我搜索了互联网和StackOverflow以获取解决方案，并尝试了我读过的所有内容，但仍然无法让Sphinx返回任何结果。这是我得到的。任何帮助，将不胜感激。带有PHP的Spinx地理距离不会返回结果

表：

与纬度和经度的位置表由谷歌的地理编码API填充。

CREATE TABLE IF NOT EXISTS `locations` (
    `sid` int(11) NOT NULL AUTO_INCREMENT, 
    `name` varchar(75) NOT NULL, 
    `latitude` float(10,6) DEFAULT NULL, 
    `longitude` float(10,6) DEFAULT NULL, 
    PRIMARY KEY (`sid`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=26 ;

查询“Select sid，latitude，longitude FROM locations”回报：

(1, 29.8986, -95.4831), 
(3, 30, -95.25), 
(4, 47.7313, -122.177),

的sphinx.conf

source Location 
{ 
type = mysql 
sql_host = localhost 
sql_user = sphinx 
sql_pass = password 
sql_db = database 
sql_port = 3306 
sql_query_pre = set names utf8 
sql_query_pre = set session query_cache_type=OFF 

sql_query = select sid, radians(longitude) as longitude, radians(latitude) as latitude, 
name from locations 

sql_attr_float = longitude 
sql_attr_float = latitude 
sql_attr_uint = sid 
    #my unique id is sid rather than id 

sql_ranged_throttle = 0 

sql_query_info = select * from locations where sid = $id 
} 

{ 
source = Location 
path = /var/lib/sphinxsearch/data/Location 
docinfo = extern 
mlock = 0 
morphology = none 
min_word_len = 1 
charset_type = utf-8 
charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F 
ignore_chars = U+00AD 
html_strip = 0 
enable_star = 0 
}

我的PHP代码：

$Sphinx = new SphinxClient(); 
$Sphinx->setServer(SPINX_SERVER, SPINX_PORT); 
$Sphinx->SetConnectTimeout(1); 
$Sphinx->SetArrayResult(true); 
$Sphinx->SetMatchMode(SPH_MATCH_ALL); 
$Sphinx->SetLimits(0,100); 

//The lat and lng input is typically provided by google geocode api but I wrote these in  static to keep things simple. 
$lat = (float) 29.7601927; 
$lng = (float) -95.3693896; 
$radius = 10000; 

$Sphinx->SetGeoAnchor('latitude', 'longitude', deg2rad(floatval($lat)), 
deg2rad(floatval($lng))); 
$Sphinx->SetSortMode(SPH_SORT_EXTENDED, '@geodist ASC'); 


$Sphinx->SetFilterFloatRange('@geodist', 0.0, floatval($radius)); 


$result = $Sphinx->Query('', 'Location');

个

结果：

Array(
       'error' => '', 
       'warning' => '', 
       'status' => (int) 0, 
       'fields' => array(), 
       'attrs' => array(
           'longitude' => (int) 5, 
           'latitude' => (int) 5, 
           '@geodist' => (int) 5 
       ), 
       'total' => '0', 
       'total_found' => '0', 
       'time' => '0.000' 
)

尝试以下：

替换代码

$Sphinx->SetGeoAnchor('latitude', 'longitude', deg2rad(floatval($lat)), deg2rad(floatval($lng))); 
$Sphinx->SetSortMode(SPH_SORT_EXTENDED, '@geodist ASC'); 


$Sphinx->SetFilterFloatRange('@geodist', 0.0, floatval($radius));

下面

$Sphinx->SetGeoAnchor('latitude', 'longitude', (float) deg2rad($lat), (float) deg2rad($lng)); 
$Sphinx->SetSortMode(SPH_SORT_EXTENDED, '@geodist ASC'); 


$circle = (float) $_radius * 1.61; 
$Sphinx->SetFilterFloatRange('@geodist', 0.0, $circle);

这已经在这里找到答案： http://sphinxsearch.com/forum/view.html?id=11038

基本上，狮身人面像索引至少需要一个全文字段才能起作用。仅由属性组成的索引不可用。

Sphinx的最新版本将在索引时发出错误，但早期版本只是默默地创建了一个无功能的索引。
