When you perform a search, Doc Assistant retrieves results by looking for the searched keyword in the index files that store all search-related data.
Doc Assistant automatically creates a search index if the search index is missing or broken in the <installation_dir>/doc directory and displays a notification in the Notifications list.
On a Linux machine, if you don't have write permissions to the Doc Assistant install directory, set the CDA_HOME_AUTOINDEX environment variable to true to create the search index in the user home directory.
On a Windows machine, Doc Assistant creates a search index in the user home directory by default. To disable this behavior, set the CDA_DISABLE_HOME_AUTOINDEX environment variable to true.
