Querying data

You can use grep, exact text, or a regex expressions to search for specific data within the Livetail.

The following example shows how text and regex searches can be combined. First, a case-insensitive regex search of mydata.io is done. The search results are then filtered with an exact text search of schemas. Finally, a case-insensitive search of TimE is applied to the filtered results.

| grep -i mydata\.io | grep "schemas" | grep -i TimE
