Method Summary

IEnumVariantSimple	crawl(ITrackCancel pTrackCancel) Traverses a data store and returns a enumeration of crawled data source items.
int	getCrawlerItemType() The type of the data source item returned by this crawler.
String	getFilter() A string expression that allows the data source crawler to filter out invalid items.
ITimeExtent	getTimeExtent() The range of allowed time value associated with crawled data source items.
boolean	isCanFilterByExpression() Indicates whether the data source crawler can filter items by a string expression like a wild-card filter or SQL Where Clause.
boolean	isCanFilterByTime() Indicates whether the data source crawler can filter items by time using the 'TimeExtent' property.
void	setFilter(String pFilter) A string expression that allows the data source crawler to filter out invalid items.
void	setTimeExtentByRef(ITimeExtent ppTimeExtent) The range of allowed time value associated with crawled data source items.
