howto use multiple bilingual thesauri for faceted search ?
We have a 3.6.0 geonetwork engine running in a docker stack, connected to
We have a hierarchical bilingual (French, English) Skos thesaurus used for
the selection of keywords for our metadata records
We have 2 specialized hierarchical thesauri containing subsets of our main
thesaurus. We want to use these 2 thesauri for faceted search.
The 2 facets (associated to the specialized thesauri) were declared in the
configuration files (config-summary.xml , config-spring.xml)
The GN behavior is somewhere confusing and we require help to the community
• When the UI is English, both facets appear in the search
interface, and we are able to select concepts in both facets
• When the UI is French, only one facet appears and it is incomplete
(only a subpart of used keywords are displayed in the UI.
We tried a lot of stuff in order to find what’s is going wrong, but we
cannot identify what’s wrong.
In the log, we noticed several errors like the one below
« Error auto-detecting language: no features in text
com.cybozu.labs.langdetect.LangDetectException: no features in text «
We are wondering if somebody has experience with the use of sub-thesauri
facet search ?
There are many other questions around this topic :
• Is there a limitation of the number of thesauri that can be we can
upload in a single GN node ?
• Is there a flag we could activate to default to English if a
keyword isn’t translated into the UI selected language ?
• When we use the directories approach to store contact description,
there is no multilingual template proposed. It’s therefore mandatory to edit
each record and insert a translation for the organisation name. If we don’t
record this translation, the facet named OrgName is not displayed. Could it
be possible to default the viewer to the English label ?
