elasticsearch - 多匹配布尔提升

Question

我正在尝试执行以下操作

curl -X POST localhost:9200/magento/customer/_search?pretty=1 -d '
{
    "query": {
        "bool": {
            "must": [

它在 Johnnie BrousXXXX（已编辑）之前向我返回了 Johnnie SultXXXX 的结果。

似乎没有正确应用提升？我试过在布尔值上查看弹性搜索文档： http ://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html

他们有一个没有任何意义boost的节点下，你通常想提升一个特定的布尔值...？boolshould

更新：

创建索引时我没有创建任何字段映射。

以下是 的结果explain：

我知道shoulds 是匹配的，因为没有它们，我得到的第一个结果与使用它们不同。

我希望我phrase_prefix在这种情况下正确使用。从文档中我并不完全清楚。此页面引用它们（http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-match-query.html#_match_phrase_prefix），但仅在常规上下文中query，而不是在multi_match.
