如何在 Lucene 7.4.0 中进行多查询搜索？

Question

I have two queries, one of them is boosted, and I want to combine them into one new query. I understand that in older version of Lucene you can do it with BooleanQuery using add . But in the version I'm using, that method seems to no longer exists. So how do I do it now?

Answer 1

To add queries into a 'BooleanQuery', now I have to use the 'Builder'. So if I want to add queries, the code line should be something like new BooleanQuery().Builder().add(query1).add(query2).build()

Yes, I should've read the migration guide first.

Also if I want to combine a boosted query and a normal one, I could just concate the strings.
