【问题描述】:
经过相当多的尝试和网络研究,我对这个查询感到疯狂。我想在 MongoDB 上的 php 中围绕地理点(距离最大 500 米)构建“俱乐部”查询。 但是当我运行查询时,它会忽略距离限制并显示数据库中的所有俱乐部,但按距离排序。
这是我的数据集(2dsphere index geoLoc):
{"_id":ObjectId("547c649e30afe32c23000048"),"name":"Club Ritzz","category":"Club","category_list":[{"id":"191478144212980","name":"Night Club"}],"location":{"city":"Mannheim"},"geoLoc":{"type":"Point","coordinates":[8.473665839156,49.484065272756]}}
{"_id":ObjectId("547c649f30afe32c2300004a"),"name":"Das Zimmer Mannheim","category":"Club","category_list":[{"id":"191478144212980","name":"Night Club"}],"geoLoc":{"type":"Point","coordinates":[8.4709362941178,49.487260552592]}}
{"_id":ObjectId("547c64ab30afe32c23000063"),"name":"Nationaltheater Mannheim","category":"Arts/entertainment/nightlife","category_list":[{"id":"173883042668223","name":"Theatre"}],"geoLoc":{"type":"Point","coordinates":[8.4776534992592,49.48782606969]}}
{"_id":ObjectId("547c64a130afe32c2300004f"),"name":"SOHO Bar Club Lounge","category":"Club","category_list":[{"id":"191478144212980","name":"Night Club"},{"id":"164049010316507","name":"Gastropub"}],"geoLoc":{"type":"Point","coordinates":[8.4630844501277,49.49385193591]}}
{"_id":ObjectId("547c64a730afe32c2300005a"),"name":"Loft Club","category":"Club","category_list":[{"id":"191478144212980","name":"Night Club"},{"id":"176139629103647","name":"Dance Club"}],"geoLoc":{"type":"Point","coordinates":[8.4296300196465,49.484211928258]}}
这里是我的 php 代码(12 月 2 日更新):
$qry = $pub->find(
array( '$and' =>
array(
array( 'geoLoc' =>
array('$nearSphere' =>
array('$geometry' =>
array('type'=>'Point',
'coordinates'=>
array(
floatval($sLon), floatval($sLat)
)
),
'maxDistance' => 500
)
)
),
array( '$or' =>
array(
array( 'name' => new MongoRegex("/.*club/i")),
array( 'name' => new MongoRegex("/.*zimm/i"))
)
),
array('$or' =>
array(
array('category_list.name' => 'Night Club'),
array('category_list.name' => 'Dance Club'),
array('category' => 'Club')
)
)
)
),
array('id' => 1, 'name' => 1, '_id' => 0)
);
有人知道为什么结果不限于指定的maxDistance吗?

奇怪的是,如果我使用像 mongoQM 这样的 ODM 包装器,那么距离搜索工作正常......
