Sorting Elasticsearch精确结果在第一次搜索时不返回
我添加了一些产品,如“lcd apple iphone 11”“lcd apple iphone x”“lcd apple iphone xs”“lcd apple iphone xr”“lcd samsung s8”“lcd samsung s8+”“lcd apple iphone xs max”“lcd apple iphone xr电池”,我们在去年添加了iphone xr产品 我已经创建了elasticsearch索引Sorting Elasticsearch精确结果在第一次搜索时不返回,sorting,elasticsearch,resultset,exact-match,Sorting,elasticsearch,Resultset,Exact Match,我添加了一些产品,如“lcd apple iphone 11”“lcd apple iphone x”“lcd apple iphone xs”“lcd apple iphone xr”“lcd samsung s8”“lcd samsung s8+”“lcd apple iphone xs max”“lcd apple iphone xr电池”,我们在去年添加了iphone xr产品 我已经创建了elasticsearch索引products\u idx1和类型product 当我搜索像苹果i
products\u idx1
和类型product
当我搜索像苹果iphone xr这样的产品时,它会返回iphone xr,但不会出现在顶部结果
我想要什么
精确结果应该是第一个,然后部分结果应该在精确结果之后。我想根据精确结果对结果进行排序
这是我在php elasticsearch中的代码
<?php
use Elasticsearch\ClientBuilder;
require 'vendor/autoload.php';
$client = ClientBuilder::create()->build();
$values =['name','name.prefix','name.suffix','sku'];
$params =
[
'client'=>['verify'=>1,'connect_timeout'=>5],
'from'=> 0,
'size'=>25,
'body' =>[
'query' => [
'bool'=>
[
'should'=> [[
'multi_match'=> ['query'=>'apple iphone xr','type'=>'cross_fields','fields'=>$values,'operator'=>'AND']
],
['match'=>['all'=>['query'=>'apple iphone xr','operator'=>'AND','fuzziness'=>'AUTO'] ]]
]
]
],
'sort'=>['_score'=>['order'=>'desc']],
],
'index'=>'products_idx1'
];
$response = $client->search($params);
echo "<pre>";print_r($response);
您可以使用with分析文本并从分析的文本中创建短语查询
添加带有搜索查询和搜索结果的工作示例
搜索查询:
"hits": [
{
"_index": "test",
"_type": "_doc",
"_id": "5",
"_score": 1.8850331,
"_source": {
"title": "iphone xr"
}
},
{

"_score": 0.30396554,
"_source": {
"title": "lcd apple iphone 11"
}
},
{
"_index": "test",
"_type": "_doc",
"_id": "2",
"_score": 0.30396554,
"_source": {
"title": "lcd apple iphone x"
}
},
{

}
},
{
"match_phrase": {
"title": "iphone xr"
}
}
]
}
}
}
搜索结果:
"hits": [

]
}
},
{
"match_phrase": {

}
}
]
}
}
}
您还可以使用多重匹配使用搜索查询
{
"title" : "lcd apple iphone xr"
}
{
"title" : "lcd apple iphone 11"
}
{
"title" : "lcd apple iphone x"
}
{
"title" : "lcd apple iphone xs"
}
{
"title" : "iphone xr"
}
虽然bhavya的答案是可行的,但它更复杂,因为它使用了match_短语
查询,根据您可能拥有的数据集,该查询更复杂,成本也可能更高,我已经创建了一个更简单的查询版本,它可以工作
索引样本文档
{
"query": {
"bool": {
"should": [
{
"match": {
"title" : "apple iphone xr"
}
},
{
"match": { --> simple additional match clause solves issue.
"title": "iphone xr"
}
}
]
}
}
}
使用其他更简单匹配子句的搜索查询
"hits": [
{
"_index": "64129903",
"_type": "_doc",
"_id": "6",
"_score": 1.8347404, // note score is higher than other results.
