    • scope: "scope query" has the same effect as "intersection query", but does not participate in the document query score (QDS)
    • exclusion: "exclusion query" is the result of a subset operation of the search results of "main, intersection, scope query" and the search results obtained by "exclusion query"
    • rerank: "rerank query" does not affect search results, but is used to change the qds value. Available query types include simbst and proxrank
