Understanding the Index Option Configuration
The word query configuration allows you to add some extra indexing options from the ones that are currently set in the database configuration. Adding any index options to the word query configuration does not add those options to the element-based index options.
To add a particular index option to word query, you check the box corresponding to the index option. Adding any index options that are not enabled in the database configuration will cause new and updated documents to use the new indexing for word query, and will trigger a reindex operation if reindex enable is set to true in the database configuration.
Options that are enabled in the database configuration appear in bold on the word query configuration. If you check the box next to an option with bold-face type, it does not change your configuration. However, if you subsequently disable that index option in the database configuration, it will remain enabled for word query as long as the box is checked.
