I have a page with a file link content element. When I add a new (pdf) file or override an existing, the index data of this page is not updating. I have to delete the index data manually at the indexing module to get it work. I could live with that, if the editor of the webpage could use this module too. But I cannot unlock this module für my editors, because it's missing at the module list.
EXT:indexed_search backend module is per default registered with admin access only.
You can change the current configuration for registered module in your custom site package extension in ext_tables.php for indexed_search module access for editors with following line:
$GLOBALS['TBE_MODULES']['_configuration']['web_IndexedSearchIsearch']['access'] = 'group,user';
Then you can unlock this module für your editors.
