disjunction between two attributes

[cinkova]

Dear developers, how can I ask for a node that either has upos=NOUN or feature value Possessive=Yes? The documentation mentions only disjunctions between values of the same attribute, and the options at hand just do not work for me.

This is now available in the last version (1.14) of Grew (see doc) and in Grew-match.
A disjunction can be used to describe a node, using the | symbol.

For instance, the following request corresponds to what you asked:

pattern { N [upos=NOUN]|[Possessive=Yes] }

Run the request on UD_Maghrebi_Arabic_French-Arabizi@2.12 (the only treebank in 2.12 using feature Possessive=Yes).
