I use content type with a term reference field. I would like users to search by taxonomy terms in that field so I keep the field visible in the main node display. However due to other reasons I would like to hide these terms from the view but keep the content searchable by these terms.
For example I would like to have synonyms searchable I will keep in my term reference field but I don't want users to see all possible variant of the word.
How to hide taxonomy terms from the node display and still have them indexed by Drupal search?
