Background
The AdvancedSearch feature enhances Special:Search through an advanced parameters form. This new interface was available as a beta feature from the end of 2017, with more than 40.000 users across all wikis. Since November 2018, it's a default feature on all wikis, including Commons.
Description
The Advanced Search extension consists of "Advanced Parameters" and "Search in (namespace)." Some of the functionality of Advanced Parameters overlaps with the new search capabilities for Structured Data, such as file type (image vs video vs audio). "Search in (namespace)" works as intended for plain text searches, but is incompatible with Structured Data searches (in that SD will not search any of those namespaces).
Questions we need answers to as we add structured data search features to Commons
- How much can we customize advanced search for structured data searches?
- If we customized it on Commons, would it affect other wikis?
- Can we turn off individual components or is it all or nothing? For example, can we not show "Search in" (for statements) since it doesn’t make sense?
