它在 Johnnie BrousXXXX（已编辑）之前向我返回了 Johnnie SultXXXX 的结果。
似乎提升没有正确应用？我尝试查看有关布尔值的elasticsearch文档：http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html
他们有boost在下面bool节点实际上没有任何意义，您通常想要提升布尔值中的特定一个shoulds...?
UPDATE:
我在创建索引时没有创建任何字段映射。
这是一个结果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有它们时不同。
我希望我正在使用phrase_prefix在这种情况下正确地。从文档中我并不完全清楚。此页面引用了它们（http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-match-query.html#_match_phrase_prefix 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, not a multi_match.
