There may be certain search suggestions that you do not want to see. You can easily remove them by placing them on the blacklist. To do this, click on 'Manage blacklist' at the right top corner in the suggestions module:
NOTE: the search suggestion will not be removed from the list of established suggestions.
By clicking on Manage blacklist, you can also see which suggestions are on the blacklist. You can also add search terms using wildcards. A wildcard allows you to place, for example, all suggestions that contain a certain term on the blacklist at once. You can do this using an asterisk (*):
Example: you want to blacklist the suggestion 'book'. This gives you the following options:
book: everything that matches 'book' exactly
book*: everything that starts with 'book'
*book: everything that ends with 'book'
NOTE: Blacklist suggestions do not work for manual suggestions. If you added a manual suggestions and also put it on the blacklist (for example by using a wildcard), then it will still be shown.
