Try our new QuickRank™ Search (it’s also our default search)
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Just type in your key word(s), like mad cow disease
(no need for quotes, we phrase-search by default), and select ![Begin Search](/peth04/20041015005345im_/http://science.gov/images/begin.jpg) |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
You’ll get results ranked in relevancy clusters, or grouped in a way most likely to match your search query.

Unlike many search engines, our results are retrieved in real time, so it could take a minute. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Our progress bar will time out in 50 seconds. This means that if a particular database is running slow, you may not get all those results during that search session. |

Search tips
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Full-text searching is available when supported by the agency’s database. |
|
You’ll know the full-text PDF is available when you see the PDF icon . |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
"And" and "Or" operators are generally supported (for example, searching frogs or toads returns results with either or both words). |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
There’s no need to use quotes for phrases – we phrase-search by default. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Wildcard character * (asterisk) is supported in several, but not all, databases (for example, ecolog* will find both ecological and ecology). |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Search is not case sensitive (for example, RAIN, Rain, and rain will produce the same results). |

Additional QuickRank™ Features
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Our special QuickRank™ formula filters results, sending you the most relevant returns. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
This means that the number of QuickRank returns may differ from the number of raw returns from the individual agency listing, which aren’t filtered by QuickRank. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Results will be returned in relevancy clusters : indicates very high relevancy, indicates high relevancy, indicates medium high relevancy, indicates low relevancy. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Our QuickRank filter is based on placement of key words: If your key word is not in a prime location in the document, likely the result won’t be ranked. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
Your results will contain top tier databases in terms of relevancy. But, you can also visit the for further investigation. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
If your search only returns three (3) or fewer ranked results, we’ll send you directly to our display by agency. |
![arrow](/peth04/20041015005345im_/http://science.gov/images/rightarrow1w.gif) |
We’ll be enhancing our ranking system soon — keep a look out for science.gov 3.0. |
