Null search swapper
We have already learned tokens and the use of eval tokens; now we will learn to use conditional tokens to set and unset the search query of a panel depending upon the result of the conditional tokens. Conditional tokens work similarly to an if loop used in programming languages. In a null search swapper, we will set tokens from the search manager to control behaviors on the page. Each search result outputs metadata around the search, the job, the server, and even the results. This feature helps users to access and set tokens from that metadata to be used throughout the page.
The null search swapper can be used to hide visualization if the result of a search query is null/empty. This kind of customization can be very useful when building highly dynamic dashboards for enterprises. For instance, the null search swapper can be used to hide a specific panel if the search result outputs nothing. So, since now the output is available instead of occupying space in the dashboard...
