Without the need to recompile Datafari or DatafariUI, you can add new suggesters in the autocomplete just by declaring them in the config file, as long as you do not want to declare a new type of suggester used in the backend (see the next chapter for adding a new type of suggester). You can get the list of currently implemented suggesters types by looking at this file: https://gitlab.datafari.com/datafari-community/DatafariUI/-/blob/dev/src/Components/SearchBar/Autocompletes/Suggester/useSuggesters.js
You also need to add the suggester into the file $DATAFARI_HOME/tomcat/conf/entity-autocomplete.properties see Adding entity autocomplete: from indexation to autocomplete and Autocomplete with Categories/Entities Configuration for more information for the configuration.
In the configuration below, we have 3 suggesters : 1 of type basic and 2 of type entity. The difference between the 2 entities suggesters here, is at the field, the name of the request handler used and titles parameters level, but it could also be at the subtitle level.

This requires developing new components in DatafariUI. Refer to the DatafariUI read me for more information on how to do that.
