I want to use tag cloud as a filter in a dashboard for histograms and display substrings in cloud.
I've added a script to JSON input field
"inline": "doc['_index'].value.substring(3) ",
Let "123indexname" be an index name.
After adding that JSON input it displays "indexname" in tag cloud
When I click on this tag in a dashboard, the filter condition "_index = indexname" appears there. But I want to filter it by full name. So "_index = 123indexname" condition should appear after click on "indexname" tag in tag cloud.
How to do it?
