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
Edit Search Sets
The Edit feature allows you to overwrite an existing query or to create a new query from a previously run query.
Use this feature to narrow the number of results that the system originally returned or to correct syntax errors in the original query.
Edit Dependent Sets
You can also edit dependent sets and search sets that include dependent sets. Dependent sets are search sets that are referenced in other sets. For example, you perform the following searches.
You decide that you want to edit set #1 to include the following search terms: TS=DNA AND TS=Nuclear DNA Fragmentation
In this instance, set #3 is a dependent set and the system automatically re-runs the search query when you edit set #1 and save the query. The Search History table now displays the following results.
Note: The numbers in the Results column in this example do not reflect the actual number of results that the system may return after you edit a set.
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
This feature allows you to save your search queries to a search history file that you can retrieve and open at a later date.
Click the Save History / Create Alert button to go to the Save Search History overlay dialog where you can save your work to the host server or to your local workstation.
You can save up to 40 search sets from the Search History table. A search history contains the search query and the selected settings for each search query.

Save a Search History as an Alert
If your organization subscribes to the alerting service, you can save a search history as an alert. You must have a subscription to Web of Science Core Collection to save a search history as an alert
The alert automatically searches the last update to the database, and then sends all relevant results to you by e-mail. For example, if your search history is on Nanotechnology, the system will send you all new works on this topic.
Note: Alerting is not available for searches that you created from an All Databases. When you go to the Search History page after performing an All Databases search, the button is simply called Save History".
Open Saved History
You cannot perform a search on a search history that contains a chemistry query that was created in a previous version of Web of Science. You need to recreate a new chemical structure using the Accelrys JDraw applet that we provide on the Structure Search page.
You cannot copy and paste a chemistry query that you created from a previous version of Web of Science or from other drawing tools such as ISIS Draw. You must use the Accelrys JDraw applet that we provide in the Structure Drawing box to create all structure drawings.
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.
Advanced Search Examples
Set Combination Search Rules
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.
Using Web of Science Categories
Use Web of Science Categories with the Advanced Search WC field tag to narrow your search to specific fields of study.
WC=(Anthropology AND Archaeology) finds all records in which both categories in the query must appear in the Web of Science Categories field within a Full Record.
