crawler.accept_files

This is a comma-separated list of file extensions that will be downloaded by the crawler. It is normally left empty, so that the crawler will accept all valid content regardless of the suffix.

Set this configuration key in the search package or data source configuration.

Use the configuration key editor to add or edit the crawler.accept_files key, and set the value. This can be set to any valid List<String> value.

In this example a specific list of filetypes (based on suffix) is listed - only files of these types will be downloaded.
