Heyla, I am new to Elastic, but having loads of fun already. I am analyzing a spreadsheet and have already created a Dashboard I am using for my team to look at. It is truly amazing what I can do out of the box after importing the csv data with the machine learning module. I read a few tutorials, but I could not really find what I am looking for.
I have two things I would like to change (mapping) though without destroying my dashboard. I don't want to remove my current index with the visualizations I already got out of it. So the question is how do I change mapping on my current index or rather how do I preserve the current index.
I have one column (field) that is indexed as text and thus makes it non-aggragatable. I understand I need to change that to keyword. No idea why it is indexed to text. Other similar columns were just indexed to keyword.
I have a date column with flat dates formatted like '1-Aug-2018'. I tried to change the field type during import, but that threw an error. As far as I have experimented it is currently not recognized as date field. What can I do to convert that back to 'date'?
....and all of that without losing my current dashboard. I would really appreciate if someone can point me in the right direction.
