ElasticSearch funtion_score类似于Solr中的查询

Question

I am migrating from ES to Solr. I had used function_score query in ES searching for the same in Solr now but couldn't find any. Does Solr support anything like function_score query-dsl-function-score-query

Answer 1

Function queries enable you to generate a relevancy score using the actual value of one or more numeric fields. Function queries are supported by the DisMax , Extended DisMax , and standard query parsers.

Function queries use functions . The functions can be a constant (numeric or string literal), a field , another function or a parameter substitution argument. You can use these functions to modify the ranking of results for users . These could be used to change the ranking of results based on a user's location, or some other calculation.

Yes. Solr supports function queries. You can find the solr official documentation Function Queries for more detailed information.
