[ENH] Index, Trackers-DynamicList field : Add to the search index the text of the item field instead of the item ID
Backport from !2464 (merged)
Avan.tech ticket : https://avan.tech/item90156
The value of the DynamicList field of the item is not found in the search result of in a search (global or customSearch). This is because Tiki is only indexed the linked ID (tracker_field_exampleHere), and not the text version (tracker_field_exampleHere_text).
