A method for determining a recrawl schedule of items on an intranet using a search appliance includes estimating, using the search appliance installed on the intranet, a change period for items on the intranet using a history of crawl information for the items. The change period for an item may be a frequency of change in content of the item. The method includes calculating a crawl period for each of the items, where the crawl period for an item is set relative to the change period for the item. The method includes determining whether to adjust the calculated crawl period for each of the items using adjustment criteria, adjusting the calculated crawl period for selected items determined for adjustment using the adjustment criteria and creating a recrawl schedule of the items on the intranet using a recrawl time for each of the items.
