When running a query in Drill, the /profiles page will show the search (and pagination) capabilities only for the top most visible table (i.e. Running Queries ).
The Completed Queries table will show the search feature only when there are no running queries. This is because the backend uses a generalized freemarker macro to define the seach capabilities for the tables being rendered. With running queries, both, running and completed queries tables have the same element ID, resulting in the search capability only being applied to the first table.
