# Advanced Within the advanced settings, it is possible to personalize which collections will remain hidden from the search function. ### Exclude collections Enter the collection handle of a collection you wish to exclude from searches. These can be special collections created for demonstration, wholesale, etc. The collection handle is found in the Search engine listing section of the Collection (bottom) set up in the Shopify admin:

### Exclude collections if they contain Wildcard exclusion. Use this for autogenerated collections, Siblings, etc. This setting also uses the collection handle. However, only a portion of the handle. For example, if your sibling collections all begin with `siblings--` followed by unique names, then you can add `siblings--` or even `sibling` here.
