Search Feature that set google apart from others part- 2

Continuing the previous post where i had written about four categories of search feature, Now the next four are- Health search, trip planning, query refinement, search by number.

Health Search

• Health Conditions

  To see information about a common disease or symptom, enter it into the search box and we’ll return the beginning of an expert summary. You can click through to read the entire article.
  
  Example:

• Medications

  To see information about most generic and brand name prescription drugs in the U.S., enter the drug name into the search box, and we’ll display a summary and description of that medication. You can click through links from the National Institutes of Health to get more information about side effects, how to take the medication, precautions, dietary instructions, and what to do if you miss a dose.
  
  Example:

• Poison Control

  You can quickly find the U.S. poison control hotline (1-800-222-1222) by entering “poison control” or similar phrases into the search box.
  
  Example:

• Suicide Prevention

  You can quickly find the phone number for the National Suicide Prevention Lifeline (1-800-273-8255) by entering "suicide prevention" or similar phrases into the search box.
  
  Example:

• Flu Vaccine Finder

  During flu season, search for “flu” to find tips on how to stay healthy from U.S. Health and Human Services and a flu shot locator which uses Google Maps to show you nearby locations offering seasonal and/or H1N1 flu vaccine.
  
  Example:

Trip Planning

• Flight Tracking

  To see flight status for arriving and departing U.S. flights, type in the name of the airline and the flight number into the search box.
  
  Example:

• Flight Schedules

  To see flight schedules to or from a particular destination, type “flights from” or “flights to” followed by the city or airport of interest. You can also add another location with “to” or “from” and view the schedule for a specific route.
  
  Flight schedule data is provided by OAG and QuickTrip by Innovata.

Query Refinements

• Related Search

  To search for web pages that have similar content to a given site, type “related:” followed by the website address into the Google search box.
  
  Example:

  Example:

Search by Number

• Package Tracking

  You can track packages by typing the tracking number for your UPS, Fedex or USPS package directly into the search box. We’ll return results that include quick links to easily track the status of your shipment.
