Advanced Search

Search for records by using field tags, set combinations, or a combination of both. For example: TI=Global Warming finds records in which the terms "global" and "warming" appear in the same record. The two terms do not have to appear in the same sentence or paragraph.

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.

The format of an Advanced Search query consists of one or more field tags and a search string. Search operators and wildcards are allowed.

Use an equal sign (=) with a field tag along with a wildcard to broaden your search. For example, SO=Cell Biology* finds the following journals (along with other published works) that begin with the terms Cell Biology in its name.

  • Cell Biology International
  • Cell Biology International Reports
  • Cell Biology Research Progress,

Using Advanced Search

  1. Go to the Current Limits section of the search page if you need to change your search settings. For example, you can change your timespan or you can turn on or off the Lemmatization feature.

  2. Enter your search query in the Advanced Search text box using the two-character field tags.

  3. Click Search.

  4. In the Search History table, click the link in the Results column to go to a Results page in order to view the results of your 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. This feature also lets you overwrite or create a new query from a previously run set combination.

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

  1. Go to the Current Limits section of the search page if you need to change your search settings. For example, you can change your timespan or you can turn on or off the Lemmatization feature.

  2. Click the Edit link under the Edit Sets column in the Search History table. The product takes you to the text box at the top of the page. The color of the Advanced Search page turns a shade of blue.

  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. If you select Create new set, a new set will appear in the Search History table.

  4. Enter your search query in the Advanced Search 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.

Did You Know ... That if you launch the Edit Set function from the Search History page, the product opens the Advanced Search page in Edit mode and keeps you on the Advanced Search page when you complete the Edit function?

Did You Also Know ... That you can save your edited search sets as an Alert?

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.

Set

Results

Description

Edit
Sets

#3

128,000

#1 AND #2

Edit

#2

539,000

TS=RNA

Edit

#1

943,000

TS=DNA

Edit

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.

#2 NOT #3

Finds all records in set #2 that are not in set #3.

#2 OR #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 page 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 limits for each search query. For example:

Topic=(Risk Factors) AND Author=(Cagnin A)
Databases=SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, BKCI-S, BKCI-SSH, CCR-EXPANDED, IC Timespan=All Years
Lemmatization=On

See Save Search History for more information about this feature.

index

Saving a Search History as an Alert

If your organization subscribes to the alerting service, you can save a search history as an alert. The alert automatically searches the latest 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 search in Web of Knowledge. When you go to the Search History page after performing an All Databases search, the button is simply called Save History".

index

Open Saved History

  1. From the Search History page, click the Open Saved History button in the Search History table to go to the Open / Manage Saved Searches page.

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

  3. After you open the search history file, the product takes you to the View History page. Click the Run Search button.

  4. If desired, change your timespan, search, and results settings.

  5. Click the Continue button to go to the Search History page.

  6. Click the number link under the Results column to go to the Results page where you can view and output your records.

index

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

  • Select the check box in the Delete Sets column of the unwanted search query, and then click Delete.

Or

  • Click the Select All button to select all search queries, and then click Delete.

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.

Search Language

All searches must be in English even if you select Chinese Simplified or Japanese as the interface language. The results of your search are always in English.

Set Combination Search Rules
  • Include a number (#) sign before each set number.

  • Include Boolean operators (AND, OR, NOT) in set combinations.

  • Do not use the SAME operator or wildcards in set combinations.

  • Use parentheses to override operator precedence.

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 records in which both research areas must appear in the Research Areas field within a Full Record.

index

Using Web of Science Category Terms

Use Web of Science Category terms with the Advanced Search WC field tag to narrow your search to specific fields of study.

For example, WC=Anthropology AND Archaeology finds records in which both subject categories must appear in the Web of Science Category field within a Full Record.
