Good evening I have to modify the geonetwork mask of the search medatada area on the left side in order to add other queries for a more specific research.
I have studied carefully the doc about the schema plugin and I have already searched through geonetwork source even all the java classes within the kernel, the lucene classes within too but it's not the point, how do I achieve it?
Every point of direction I should follow is welcome
Thank you
Nicola
