Advanced Search enables you to form and combine search sets. For example:
Set #3 consists of records in which cell death or apoptosis appears in the Title and Japan or Russia appears in the Addresses field.
An advanced search usually begins with at least two queries consisting of search terms prefaced by field tags.
The Search History table at the bottom of the page displays all successful searches that you ran during the current session. Search sets are listed in the Search History table in reverse numerical order - the most recently created set is at the top of the table.
Using Advanced Search
The search sets are listed in the Search History table in reverse numerical order - the most recently created set is at the top of the table.
To combine two or more sets:
Combining Sets (Examples)
#1 (or any set number)
#1 AND #2
#2 NOT #3
#2 OR #3
(#2 NOT #1) AND #3
(#1 OR #2 OR #4) AND #3
Save History / Create Alert
Save History/Create Alert gives you the option to save search queries and open them later.
Click Save History / Create Alert to save your search and create an alert (only available from the Core Collection database). If you want to save a search query to your local drive, click Save search history to a local drive; you can always import the file later from the Searches and Alerts page.
You can save up to 40 search sets from the Search History table. A search history contains the search query and selected settings for each search query.
At this time, alerts are not available for Compound Searches.

Save a Search History as an Alert
If your organization subscribes to our alerting service, you can save a search history as an alert.
Alerts automatically search the last update to the database and emails relevant results to you. For example, if your search history is on Nanotechnology, our system emails new works on this topic.
Open Saved History
From the Search History or Advanced Search page:
Dependent Sets: After you click Delete, the product checks for dependent sets. Selected sets that are not referenced in other sets are deleted. If, however, a set is referenced in a set that is not selected for deletion, the product returns the following error message.
In this instance, the product marks the Delete Sets check box of both the original set marked for deletion and the referenced set. You can either delete both sets or neither set.
Example 1: You create a set combination (set #3) that includes sets #1 and #2. You cannot delete set #1 because set #3 (the referenced set) is dependent on set #1. You can, however, delete both sets #1 and #3.
Example 2: You create a set (set #2) by using the Refine Results option from the Results page. You cannot delete this set because it is dependent upon the original parent set (set #1). You can, however, delete both sets.

Searching for Numerical Data
To search for numerical data from the Advanced Search, see Advanced Search: Searching the Numerical Data Field for a list of field tags that you can use in your search.
Using Research Area Terms
Use Research Area terms with the Advanced Search SU field tag to narrow your search to specific fields of study.
SU=(Biochemistry & Molecular Biology AND Biophysics) finds all records in which both research areas in the query must appear in the Research Areas field within a Full Record.
