Current implementation of tree filter methods like

query descendantsOf($node)
query branchOf($node)
query childrenOf($node)
query siblingsOf($node)
query ancestorsOf($node)
query rootsOf($node)

are adding two or more condition to the query class, but is not grouped into a parenthesis.

So we cannot do a query like


Adding parenthesis to the queries will make it easier to do such queries.

Use case:

An article has more than one categories. And we need to search for related articles which have one of the categories or their descendents as their category.


There are categories - cat1, cat1.1, cat2, cat2.1, cat2.2, cat2.3, cat3, cat3.1, cat3.2

Article 1 has categoris - cat1.1, cat2, cat3.1

Article 2 has category - cat1

Article 3 has category - cat2.2, cat1

Article 4 has category - cat3.2, cat2

So Article 1 has Article 3 (because it has cat2.2) and Article 4 (because it has cat2) as its related article.

If the tree filter methods are parenthesized, we can do this in one query
