title: How to do a multi query search in Lucene 7.4.0?
body: <p>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 <code>BooleanQuery</code> using <code>add</code>. But in the version I'm using, that method seems to no longer exists. So how do I do it now?</p>
