Filter functions

addSearchChip

This functionality allow you filter the embedded dashboard by search text.

You can search in all fields:

this.iframeElement = document.getElementById('iframe');
this.iframeWindow = (<HTMLIFrameElement>this.iframeElement).contentWindow;

let message={actionType: "addSearchChip", text: "error", index: "logstash-*"}

this.iframeWindow.postMessage(message, '*');

Or you can search in specific field(for example "severity"):

this.iframeElement = document.getElementById('iframe');
this.iframeWindow = (<HTMLIFrameElement>this.iframeElement).contentWindow;

let message={actionType: "addSearchChip", text: "severity:error", index: "logstash-*"}

this.iframeWindow.postMessage(message, '*');
