In my study I have to work with something like BooleanPolynomialRing(... 'x', 10).

After that I can create function in the form x1 + x1*x3 + ....

However I would like to create functions in more generic form like x[1] + x[2]*x[3] where x[1] is equivalent for x1, etc.

The final goal is to be able to construct functions programmatically combining indexed expressions like x[i] + x[j] etc.

Is this what you want?

sage: R = BooleanPolynomialRing(10, 'x')                                                  
sage: R                                                                                   
Boolean PolynomialRing in x0, x1, x2, x3, x4, x5, x6, x7, x8, x9
sage: x = R.gens()                                                                        
sage: x                                                                                   
(x0, x1, x2, x3, x4, x5, x6, x7, x8, x9)
sage: x[2]
