What is wrong with my Boolean expression?

Question

I've got the following expression:

A*!B*(!B*C+!C*A*(D+B*!A+D*A*B+C*!D))

After translating it to Wolfram's understandable language I got this:

A OR NOT B OR (NOT B OR C AND NOT C OR A OR (D AND B OR NOT A AND D OR A OR B AND C OR NOT D))

For some reason Wolfram shows me this message:

Wolfram|Alpha doesn't understand your query
Showing instead result for query: OR

What's wrong with it? Why Wolfram can't minimize this expression?

Answer 1

Actually I got it working by using the proper notation:

A && ~B && (~B && C || ~C && A && (D || B && ~A || D && A && B || C && ~D))
