.Bool(b => b
    .MustNot(m => m.MatchAll())
    .Should(m => m.MatchAll())
    .Must(m => m.MatchAll())
    .Filter(f => f.MatchAll())
    .MinimumShouldMatch(1)
    .Boost(2))

Object Initializer Syntax Exampleedit

new BoolQuery()
{
    MustNot = new QueryContainer[] { new MatchAllQuery() },
    Should = new QueryContainer[] { new MatchAllQuery() },
    Must = new QueryContainer[] { new MatchAllQuery() },
    Filter = new QueryContainer[] { new MatchAllQuery() },
    MinimumShouldMatch = 1,
    Boost = 2
}
