@@ -41,6 +41,7 @@ Configuration
     Value of 0 means logtrail will search in all available logs by default.
 - `display_timezone` - Timezone to display the timestamp in Event Viewer. e.g. `America/Los_Angeles`. Default value of `local` will use the timezone of browser. The time specified in `Seek To` popup will always use browser timezone.
 - `display_timestamp_format` - Format to display the timestamp in Event Viewer. For list of valid value refer [here](http://momentjs.com/docs/#/displaying/)
+- `default_search` - if specified, this will applied as default search text while launching logtrail. The value can be any search text. e.g. `ssh` - shows all logs with `ssh` in message field. or `log_level:SEVERE` - shows all logs where `log_level` field is `SEVERE`. The field name should be a valid field in elasticsearch document. The default search field is the field mapped to `message`.
 - `fields` - Edit this parameter to map the event fields in ES to logtrail fields
     - `timestamp` - maps to @timestamp field inserted by logstash. This will be used for querying internally. Logtrail recommends @timestamp to be stored in UTC in ES.
     - `hostname` - hostname from where the events were received. Also used by hostname filter. Hostname field should be of type keyword. For more info checkout [Hostname field need to be of type keyword](docs/how_to.md#1-hostname-field-need-to-be-of-type-keyword)
