Elasticsearch 搜索无效结果

Question

我添加数据添加Elasticsearch这段代码：

$data = array("name"=>HelperMC::strToUtf8(trim($name)),
        "urlname"=>HelperURL::strToURL(trim($name)),
        "price"=>number_format(HelperParser::clearTextFromPrice($price), 2, ',', '.'),
        "price_for_filter"=>HelperParser::clearTextFromPrice($price),
        "image"=>$imgname,
        "description"=>HelperMC::strToUtf8($description),
        "keywords"=>HelperMC::strToUtf8($keywords),
        "url"=>$k['url'],
        "sitemap_id"=>intval($sitemapId),
        "shop_id"=>$shop['shop_id'],
        "logo"=>$shop['logo'],
        "key"=>$hashKey,
        "type"=>intval(1),
        "shop_rating_count"=>intval($shop['rating_count']),
        "shop_rating_point"=>intval($shop['rating_point']),
        "created_at"=>date("Y-m-d H:i:s"),
        "updated_at"=>date("Y-m-d H:i:s"));

//create elasticsearch index
HelperES::insertEntry(json_encode($data),$hashKey);

我的 insertEntry 函数：

private static $elasticBase = "http://localhost:9200/shopping/items";

public static function insertEntry($data_string,$id = false){
    if($id)
        $url = self::$elasticBase."/".$id;
    else
        $url = self::$elasticBase;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL , $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    @$result = curl_exec($ch);
    curl_close($ch);

    return $result;
}

和我的搜索功能：

public static function search($keyword, $defaultOperator = "OR" ,$start = 0, $size = 25, $from = 0, $to = 10000, $shopsArr = array(),$orderBy = "price", $order = "asc"){
    $searchUrl = self::$elasticBase."/_search";

    if(count($shopsArr) > 0){
        $query = '{
                        "from" : '.$start.', "size" : '.$size.',
                        "query" : {
                            "filtered" : {
                             "query": {
                                "query_string": { "query": "'.$keyword.'",
                                "fields": ["name","urlname"],
                                "default_operator": "'.$defaultOperator.'"
                                }
                              },
                                "filter" : {
                                     "bool" : {
                                        "must" : {
                                            "terms" : { "sitemap_id" : '.json_encode($shopsArr).' }
                                        },
                                        "must" : {
                                            "range" : {
                                                        "price_for_filter" : {
                                                            "from" : "'.$from.'",
                                                            "to"  : "'.$to.'"
                                                        }
                                                      }
                                        }
                                }
                            }
                        }
                    },
                    "sort" : [
                                 {"'.$orderBy.'" : {"order" : "'.$order.'", "mode" : "avg"}}
                             ]
                }';
    }else{
        $query = '{
                "from" : '.$start.', "size" : '.$size.',
                "query" : {
                    "filtered" : {
                     "query": {
                            "query_string": { 
                                "query": "'.$keyword.'",
                                "fields": ["name","urlname"],
                                "default_operator": "'.$defaultOperator.'"
                            }
                          },
                        "filter" : {
                            "range" : {
                                "price_for_filter" : {
                                    "from" : "'.$from.'",
                                    "to"  : "'.$to.'"
                                }
                            }
                        }
                    }
                },
                "sort" : [
                             {"'.$orderBy.'" : {"order" : "'.$order.'", "mode" : "avg"}}
                         ]
            }';
    }

    echo $query;    

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL , $searchUrl);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
    curl_setopt($ch, CURLOPT_POSTFIELDS, $query); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    @$result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

但我的搜索结果无效。

不工作。

Answer 1

查看您的 shopping 索引的映射，它表明您的 price_for_filter 字段实际上是一个字符串，而不是数字类型。因此，您的范围过滤器正在进行字符串比较，而不是数字比较。这会过滤掉您的所有结果。

为了说明，您的范围是从“0”过滤到“100000”。您的第一个预期结果的 price_for_filter 值为“12.97”。在做字符串比较时，“12.97”大于“0”，但是，作为一个字符串，它也大于“100000”，所以这个结果被过滤掉了（“12”>“10”）。

您需要将 price_for_filter 字段更改为数字字段，或者您需要添加一个数字类型的新字段并更改范围过滤器以使用该新字段。
