Important: #86994 - Indexed Search indexes pages using route enhancers

See forge#86994


Because of pages that use route enhancers do not use cHash functionality in most cases, it is necessary to add the static arguments of the indexed page to generate the phash values used by indexed_search.

For administration of the indexed pages, the static arguments of the page need to be stored in the index_phash database table as well, which makes their enhancing inevitable.

In order to make indexed search work with Site Handling, update database schema using the Database Analyzer in maintenance module to add the necessary database field. Once done, the search index needs to be rebuilt.
