Filter search result per Parent Category

[Nicolas Pinçon, modificado 6 Anos atrás.]

Hi,

I would like to be able to filter a WebContent search result set with parent category.
Let me illustrate my problem with an example.
I have 1 vocabulary containing 4 categories.
Vocabulary : Countries and Cities

• Category 1 : USA
  
  • Category 1a : NYC
  • Category 1b : Washington
• Category 2 : Spain
  
  • Category 2a : Madrid

Finaly, I have a webcontent (WC1) associated with "NYC" another one associated to "Washington" (WC2) and a third one associated to "Madrid" (WC3).

When I do a search, my 3 results are shown. I would like to filter my search result per "USA" (so the "Parent category") in order to retrieve only 2 results (WC1 and WC2) :
- Is it possible only throuhgt search portlet configuration ? I have been looking in search portlet configuration but can't find the correct setting.
- Only throught custom code ? Like overriding the Liferay search portlet ?

I am using Liferay7-GA4.

Many thanks,

Nicolas
