Administrative functions related to site search functionality.

Search is implemented by several API functions, which in turn rely on an index defined in an Azure Cognitive Search service.

• Update Index
  Force updates

  Updates the index from files in the GitHub repository. If "force" is checked, then old index entries are discarded. Updates can take a while, depending on how many files have to be re-indexed.

• DESTROY Search Index

  Destroys and recreates the search index. All index data is lost, and you will have to re-index files. Usually only necessary if the related source code has changed in a way that reshapes the index in some fashion.
