Searching for Components in NI Multisim Database

I am new to Multisim and I don't know how the components are organized in the database. How do I search for a component?

I want to find a new component in multisim, where do I look for components?

To get to the Multisim Component Search engine, from the main menu select Place»Component»Search.

Additional Information

Searching by Part Number:
When you are searching by part number, it is better to search by the common part number and not full manufacturer part number. For example, if you are looking for a NE555D Timer, you should search for 555.  In addition, use the asterisk (*) wildcard to give your search a wider range.  If you just enter 555 in the Component search field, only components that start with 555 will appear in the search result.  But by using the asterisk and enter as shown below, you will find all parts with 555 and you won't miss the LM555 which is a good replacement for a NE555D.

Searching by Functionality:
Using the example of a red LED.  In the Component Search dialog, enter Red LED in the Function field and Multisim will search for that string in the component Function area as shown below.
