Saving parameters in "Data Visualization" tab leads to relaunching keyword search

Hello @x-SEbel @x-TGaliz ,

When I try to change and save the parameters for the keyword search in the Data Visualization tab, it launches a search for the text already in the textbox.

This should not happen. That is, when I click on "Save", it should only save the parameters and not launch a new search.
