I am using data tables and have joined some columns using the render feature: https://datatables.net/examples/advanced_init/column_render.html
However when I use the data tables search I only want to search the content of the original column and not the other text which has been joined using the render.
I thought I could use this https://datatables.net/examples/advanced_init/html5-data-attributes.html
However it seems to search the data-search attribute and the column contents.
How can I get the search to only search in the data-search attribute?
