Download the csv sources
Go to the Forge, open or create the mission with the network.
Open Data Explorer application
Create a new database with the name Example, set the asset name db_example

Your result should look like this. Don't forget to save the database to the network asset storage by clicking Apply Changes button.
Add a row to the result table if any cell in this row contains the defined value (case-insensitive search is used). This can be the first element in the pipeline. If it is the first element, all tables will be checked (the query will be executed against the entire database).
