你知道我做错了什么吗？下面是我的ORM映射：

/**
 * @ORM\ManyToMany(targetEntity="Foo\CoreBundle\Entity\Tag", inversedBy="tags")
 * @ORM\JoinTable(name="person_has_tags")
 **/
 private $tags;

Answer 1

所以几个月前我自己也遇到过这个问题。长话短说，弹性搜索索引正在分解标签的名称，因此“位置”不再有确切的匹配。elastic search在其索引中的内容实际上更接近于“pos”、“it”和“tion”。您要么需要让elastic search知道，以便在将对象提交索引时拆分该字段，要么只根据标记的id而不是名称进行搜索。我最终选择了id路线，因为它对我来说似乎更有效。

下面是我的代码示例，请注意，我将嵌套筛选器嵌入到布尔筛选器中，因为我有其他搜索参数，这里没有显示：

$query = new Query\QueryString('*' . $searchText .'*');
$boolFilter = new Bool();
$nestedFilter = new Nested();
$nestedFilter->setPath('categories');
$categoryFilter = new Term(['id' => $categoryId]);
$nestedFilter->setFilter($categoryFilter);
$boolFilter->addMust($nestedFilter);
$filteredQuery = new Filtered($query, $boolFilter);

和我的弹性物体的一个片段：

"name": "Sample Object",
"published": true
"categories": [
    {
        "id": 1,
        "name": "cool"
    },
    {
        "id": 3,
        "name": "awesome"
    }
]
