The Data Source Crawl Data API can be used to remove the entire crawl history for a data source. Without a crawl history, when a data source is re-crawled, all documents will be treated as "never before seen". This can be useful if field settings have been changed (such as whether the field is stored or not) and a re-crawl of content is required.
