Elasticsearch搜索数字字段

Question

I am new to elasticsearch. Apologies if the question sounds very basic. I am not able to get the answer directly from the documentations.

Is there a way to do a search on number field with the returned docs score ranked based on how close the number is to the input filter. I mean,

• if I have 10 docs in the index, let's say book objects
• and the prices of them are 1 to 10 if I search for book price of 12$
• I want to get the book of 10$ at the top and 9$ next and so forth...

Is it possible with elasticsearch?

我建议您对弹性响应进行排序，如果您必须在elasticsearch中进行处理，则可以查看stript_score函数： https ://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function- score-query.html＃function-script-score 。
