The 30 million document capacity is included as part of the largest Google Search Appliance, and requires no customization. Larger capacities are available upon request from Google.
In addition to the higher search capacity, the new Google Search Appliance also offers new advanced search functions, such as:
* Date range search: People can search for terms (such as "product information") and restrict results to a range of dates (such as between Jan. 1, 2006 to Sept. 1, 2006).
* Number range search: People can search for terms (such as "DVD player") and request results for a certain number range (such as between $100 to $500).
