弹性搜索自动完成与辅助搜索顺序

问题描述：

我只是通过弹性搜索的方式工作，需要一些帮助与自动完成功能。弹性搜索自动完成与辅助搜索顺序

基本上，我有自动完成功能工作，但我想添加使用我的人口领域降序次要排序顺序。但是，当我插入一个排序参数给我的查询时，它给了我一个400错误信息。你能看看我的映射和查询，看看它们是否设置正确，并建议我需要做些什么来完成这项工作？

很多谢谢。

映射：

PUT /ff_search_locations2?pretty 
{ 
    "mappings": { 
    "1": { 
     "_all": { 
     "enabled": false 
     }, 
     "properties": { 
     "city": { 
      "type": "text" 
     }, 
     "county": { 
      "type": "text" 
     }, 
     "region": { 
      "type": "text" 
     }, 
     "country": { 
      "type": "text" 
     }, 
     "url": { 
      "type": "text" 
     }, 
     "combined": { 
      "type": "completion" 
     }, 
     "city_lc": { 
      "type": "text" 
     }, 
     "population": { 
      "type": "text" 
     }, 
     "location": { 
      "type": "geo_point" 
     } 
     } 
    } 
    } 
}

我的工作查询：

POST /ff_search_locations2/_suggest?pretty&pretty 
{ 
    "1": { 
    "prefix": "london", 
    "completion": { 
     "field": "combined" 
    } 
    } 
}

我已经试过：

POST /ff_search_locations2/_suggest?pretty&pretty 
{ 
    "1": { 
    "prefix": "london", 
    "completion": { 
     "field": "combined" 
    } 

    }, 
    "sort": { "population": { "order": "desc" }} 
}

和返回的错误：

{ 
    "error": { 
    "root_cause": [ 
     { 
     "type": "illegal_argument_exception", 
     "reason": "suggester with name [population] not supported" 
     } 
    ], 
    "type": "illegal_argument_exception", 
    "reason": "suggester with name [population] not supported" 
    }, 
    "status": 400 
}

我使用生成索引的PHP代码：

error_reporting(-1); 
ini_set('display_errors', 'On'); 

$db = "my_db"; 
$link = mysqli_connect("localhost", "user", "pass", "$db") or die(mysql_error()); 

$result = mysqli_query($link, "SELECT * FROM search_locations6 ORDER BY Population DESC") or die(mysql_error()); 
while($row = mysqli_fetch_array($result)) 
{ 
    $ii++; 
    $i++; 

    $data_array = array("city" => $row['city'],"county" => $row['county'],"region" => $row['region'],"country" => $row['country'],"url" => $row['url'],"combined" => $row['combined'],"city_lc" => $row['city_lc'],"population" => $row['Population'],"location" => array("lat" => $row['lat'],"lon" => $row['long'])); 

    //doing it in chunks, don't feel like changing heap sizes... etc. 
    if($i < 10000) 
    { 
     $json_data = '{"index":{"_id":"'.$ii.'"}}'; 
     $json_data .= "\n"; 
     $json_data .= json_encode($data_array); 
     $json_data .= "\n"; 
     file_put_contents('bulk.php', $json_data, FILE_APPEND); 
    } 
    else 
    { 
     exec('curl --fail --silent --show-error -XPOST \'localhost:9200/ff_search_locations2/1/_bulk?pretty&refresh\' --data-binary "@bulk.php"'); 
     unlink('bulk.php'); 
     unset($i); 
    } 
}

答

排序顺序不Suggesters查询支持。建议者的重点在于速度，对混音的加入会减慢速度。

您可以将weight添加到您的查询以提高排名，但不能添加辅助排序索引。如果你正在寻找一个辅助排序，我会建议你可以使用search

编辑：纵观索引代码，你可以为你combined字段添加weight为领域。

`$data_array = array("city" => $row['city'],"county" => $row['county'],"region" => $row['region'],"country" => $row['country'],"url" => $row['url'],"combined" => array("input" => $row['combined'], "weight" => $row['Population']),"city_lc" => $row['city_lc'],"population" => $row['Population'],"location" => array("lat" => $row['lat'],"lon" => $row['long']));`

它的工作！如果你可以更新你的答案来说一些像......在你的完成类型中添加你的人口数值，如下所示：'code' $ data_array = array（“city”=> $ row ['city']，“county “=> $ row ['country']，”url“=> $ row ['url']，”=“$ row ['county']，”region“=> $ row ['region']，'country'=> “combined”=> array（“input”=> $ row ['combined']，“weight”=> $ row ['Population']），“city_lc”=> $ row ['city_lc']，“population” => $ row ['Population']，“location”=> array（“lat”=> $ row ['lat']，“lon”=> $ row ['long']））;'code' then I将它标记为正确的答案。 –

感谢您提供索引代码。更新了我的答案。 – NutcaseDeveloper
