works:

{
    query  => { match_all => {} },
    filter => {
        or => [
            { prefix => { name => "Dave " } },
            { prefix => { name => "David " } },
        ]
    }
}

also:

{
    query  => { match_all => {} },
    filter => {
        or => [
            { prefix => { name => "Dave " } },
            {
                and => [
                    { prefix => { name => "David " } },
                    { not => { prefix => { pauseid => "D" } } },
                ]
            },
        ]
    }
}

logic:
- and => []
- or  => []
- not => {}

wildcard replacements:
- start ==> prefix
- end   ==> postfix
- other ==> keep current query build
