Members

	Name	Description
	CanFilterByExpression	Indicates whether the data source crawler can filter items by a string expression like a wild-card filter or SQL Where Clause.
	CanFilterByTime	Indicates whether the data source crawler can filter items by time using the 'TimeExtent' property.
	Crawl	Traverses a data store and returns a enumeration of crawled data source items.
	CrawlerItemType	The type of the data source item returned by this crawler.
	Filter	A string expression that allows the data source crawler to filter out invalid items.
