How to use [log.query]

The reference page of log.query has its arguments, constraints and declaration.

To retrieve log items sequentially you can use [log.query]. This slot can optionally take a [from] argument being the id of an existing log item from where to start retrieving items, and a [max] argument being the maximum number of records to return. If no [max] argument is specified, the default value of this is 10. In addition the invocation can be fiven a string as its value, which if given must match the content of your log items for an item to be returned. Below is an example of usage.

log.query:"We successfully authenticated user 'root'"
   from:555
   max:20
