Class GroupQueryNodeProcessor

The ISyntaxParser generates query node trees that consider the boolean operator precedence, but Lucene current syntax does not support boolean precedence, so this processor remove all the precedence and apply the equivalent modifier according to the boolean operation defined on an specific query node.

If there is a GroupQueryNode in the query node tree, the query node tree is not merged with the one above it.

Example: TODO: describe a good example to show how this processor works
