hello I am looking for documentation on how to configure the model for pkm  :

  kmsearch_categories,

  kmsearch_tags,

  kmsearch_replacements,

  kmarticle_tag. 

the documentation I found is imcomplete 

https://academy.pega.com/topic/search-tuner/v1

https://docs.pega.com/bundle/knowledge-buddy/page/knowledge-buddy/implementation/download-taxonomy-file.html

and do not provide clear answer on my question.

• I have configured the skipword and it is working well.
• I have configured also the kmsearch_replacements and it is partly working,
  • >>meaning when I search for 1 word present in the title it is working well
  • >>meaning when I search for 2 words whith a  AND matching logic and present in the title it is working well 
  • >> when only 1 of the 2 words is in the title (other one in the article) whith a  AND matching logic , I have no results 

----------------------------------------------------------------------

I have been told that you need to install all the models 

  kmsearch_categories,  kmsearch_tags,  kmsearch_replacements,  kmarticle_tag

in order to have the research fully working well, is it right ?
