Thank you for your answer.
Do I need a Platinum license for any of the two methods you suggested?
I would like to use the basic license first to try WorkplaceSearch. Is it not possible to try that method with this license type?
First, I tried the second suggestion.
However, when I go to Organization settings > OAuth application, I get the following message
Configuring OAuth for Custom Search Applications
Configure an OAuth application for secure use of the Workplace Search Search API. Upgrade to a Platinum license to enable the Search API and create your OAuth application.
Next, I tried the first suggestion.
I followed all the steps in the following URL
When I start EnterpriseSearch, I get the following message
# ENT_SEARCH_DEFAULT_PASSWORD=passwordexample /usr/share/enterprise-search/bin/enterprise-search
