Fluent DSL example

edit
q.Query() && q.Query()
//second bool
|| (+q.Query() || +q.Query() || !q.Query() && (!q.Query() && !q.ConditionlessQuery()))
// simple nested or
&& (q.Query() || q.Query() || q.Query())
//all conditionless bool
&& (q.NullQuery() || +q.ConditionlessQuery() || !q.ConditionlessQuery())
// actual bool query
&& base.QueryFluent(q)

Object Initializer syntax example

edit
Query && Query
//second bool
|| (+Query || +Query || !Query && (!Query && !ConditionlessQuery))
// simple nested or
&& (Query || Query || Query)
//all conditionless bool
&& (NullQuery || +ConditionlessQuery || !ConditionlessQuery)
// actual bool query
&& base.QueryInitializer
