thesaurus neutral keyword selector

[pvgenuchten]

in some catalogues we now have a vast number of linked thesauri, users are not always aware which is the best thesaurus which contains the keyword they look for. improvement suggested is to add a generic keyword search box to the editor which queries the content of all thesauri, in autocomplete: for each concept found the thesaurus is mentioned in which the concept is located.

queries all thesauri by default, a optional parameter can limit the scope for that field

when saving, keywords are clustered to the relevant thesauri (update fixed info?)

assumes: thesaurus content is indexed in elastic to facilitate search

There is a allThesaurus concept made by Jesse long time ago which does that but not sure it is still working... See https://github.com/geonetwork/core-geonetwork/search?q=allThesaurus
