Advanced Search

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.

Use this feature to narrow the number of results that the system originally returned or to correct syntax errors in the original query.

1. Click the Edit link under the Edit Sets column in the Search History table. The product takes you to a text box at the top of the page.

2. Go to the More Settings section of the page if you need to change your settings.

3. Select either Overwrite existing set (default option) to edit the existing search set or select Create new set to create a new set from the existing set.

4. Enter your search query in the text box using the two-character field tags.

5. Click Search to complete the process. Click Cancel to stop the operation.

6. In the Search History table, click the link in the Results column to view the results of your search.

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.

Combine Sets

2. Select the check box under the Combine Sets column of each set that you want to combine.

3. Click the Combine button.

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

1. From the Search History or Advanced Search page, click the Open Saved History button in the Search History table to go to the Saved Searches and Alerts overlay dialog.

2. Click the Open button of the needed search history file from the host server or from your local workstation.

3. From the View History page, click the Run Search button.

4. From the Select Database(s) and Timespan page, change your timespan and settings, if needed.

5. Click the Save As My Defaults button if you want to save your revised settings so that they are available each time you open this particular search history file. This step is optional.

Caution:

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.

Delete Sets

From the Search History or Advanced Search page:

• Select the check box in the Delete Sets column of the unwanted search query, and then click Delete to remove the search history set from the Search History table.

Or

• Click the Select All button to select all search queries, and then click Delete to remove all of the search historys set from the Search History table.

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.

At least one of the sets you have selected to delete is referenced in a set combination. We have marked the affected set combinations for you. Please verify the checkmarks and click DELETE to remove the sets.

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.

Using Research Area Terms

Use Research Area terms with the Advanced Search SU field tag to narrow your search to specific fields of study.

For example:

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.

index

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.

For example:

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.
