Advanced Search Options
The search field in the Tez Queries Page supports Influx-like query statements. For example, if you want to search for a query, use the format parametername:value. However, you need to know the full name of the parameter to be able to use it. For example, the name of the parameter visible in the UI is User. However, internally, the parameter name is effective_user. Hence, if you want to search for queries with User = Mark, you need to type effective_user:Mark.
