The February 2020 release of Qlik Sense Enterprise includes the ability to ask natural language questions in the Insight Advisor providing the same functionality seen on cloud editions of Qlik Sense since September 2019.
The functionality will be enabled by default for new installations of Qlik Sense Enterprise. However, for some upgraded environments this will be installed but switched off. This due to a process being required to upgrade the internal root certificate in environments where the certificate was generated by Qlik Sense installations prior to the June 2019 Qlik Sense Enterprise release.
Customers wishing to use the NLP functionality can follow the steps under the Knowledge Base article below in order to enable NLP, recreate the root certificate, and for multi-node environments re-distribute the certificates.
