Sorry for repeating, but I have noticed that this message displays
incorrectly and just in case I'll duplicate it.

For example, when we have both or clauses and "AND" clauses together,
like x = 1 and (y =1 or y=2 or y=3 and z = 1). The structure looks like:
RestrictInfo->orclauses = [RestrictInfo [x=1],
RestrictInfo->orclauses = [RestrictInfo[y=1],
RestrictInfo [y=2],
BoolExpr = [Restrictinfo [y=3], RestrictInfo [z=1]

It'sworkingfinenow.
The error was caused by the specifics of storing the "OR" clauses in the
RestrictInfo structure. When viewing the list of or offers, we could
encounter not only the RestrictInfo type, but also the BoolExpr type.
It's working fine now.
