elasticsearch 在elasticsearch中从评分中删除增强项

elasticsearch 在elasticsearch中从评分中删除增强项,elasticsearch,boost,relevance,elasticsearch,Boost,Relevance,有没有办法,我可以从弹性相关性评分中删除默认的boost项,或者将其设为1(这样它就不会反映在评分中)。比如说, 编辑:输入查询为 GET test_index/_search { "query": { "match": { "text": "asia pacific" } },"explain": true } 部分结果如下: "details" : [ { "value" : 6.5127892, "d

有没有办法,我可以从弹性相关性评分中删除默认的boost项,或者将其设为1(这样它就不会反映在评分中)。比如说,

编辑:输入查询为

GET test_index/_search
{
  "query": {

部分结果如下:

这是一个简单匹配查询中其中一个术语的解释。 在上面的示例中,我想删除boost项2.2或使其等于1。
请建议如何执行此操作。

在查询中使用
bool->filter
而不是
bool->must
。这正是问题所在。

我目前正在使用一个简单的查询,
GET test\u index/\u search{“query”:{“match”:{“text”:“asia pacific”}}
来获取结果,但是如果我使用,
GET test\u index/\u search{“query”:{“bool”:{“filter”:{“term”:{“text”:{“text”:“asia pacific”}
,它返回0个结果。任何关于我在这里做错了什么的建议。这里已经回答了术语vs match:如果你想保持1分,请使用以下命令:
{“query”:{“bool”:{“filter”:[{“match”:{“text”:“asia-pacific”}]}}}
谢谢你的建议。但我正在努力提高1分,而且仍然需要基于BM25的TF和IDF分数。使用bool->filter->match的这种格式会给出一个恒定的分数,这与我想要达到的不同。哦,我误解了你的问题。我认为你不能选择得分部分。。。您可以通过脚本或函数分数()调整最终分数,但不能分解
匹配
评分策略。
