CRUD operations for a search index

The following sample demonstrates how you can use the API to create, update, and delete a search index and how you can perform a search operation.

IMPORTANT: The following code samples perform CRUD operations over search index files within the Search Service scope. They do not perform any actions over Sitefinity CMS publishing points associated with the search index.
