Inputlookup in dropdown to display different columns

Hi all, I'm creating a dashboard that contains drop downs that allow viewers to select a field `user_id` and the table will **display a list of user_ids and other columns' value** regarding the id. But due to security issues, I am only given a search `index=version_search` and when I edit dynamic options in drop downs, search strings return no result. All information I have now is: Index general settings: /home/data/version_search/db My source file:(pretty sure the `inputlookup search_version` is not correct because not sure if lookup tables being created) Select a user IDAll*user_iduser_id| inputlookup version_search | dedup "user_id" | fields "user_id"0 Does anyone know any possible solutions? Thanks in advance!
