Search History Table
The Search History table appears at the bottom of the Advanced Search and Search History pages for all product databases. Whenever you perform a search, the results of your search display in the Search History table.
When performing an All Databases search, the Search History table appears at the bottom of the Search History page.
What Does the Search History Table Display?
Displays the number of the search set (#1, #2, #3, etc.). Search sets are listed in reverse chronological order with the most recent search set at the top of the table.
Displays the total number of results retrieved, along with a link that takes you to the Results page.
A Chemical Structure icon indicates the record contains structure data. You must have a subscription to one or both chemical indexes in order to create structures and to search for compounds and reactions.
Search History Details Column
Displays field tags, search terms, timespan, and other information in the Search History table.
The phrase "Refined by" will appear before each set that you create using the Search within Results, Refine Results, and Analyze Results options.
View Structure Drawing Link
This link allows you to view the structure that retrieved the reactions or compounds in the results set. You cannot modify the structure image. You can, however, copy the structure and paste the image in the Structure Drawing box on the search page in order to create a new chemical search query.
Note: You must have a subscription to one or both chemical databases in order to see this link.
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.
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:
Combine Structure Searches
You can use set numbers to combine two structure searches that retrieved compound records. Similarly, you can combine two structure searches that retrieved reaction records.
Note: You cannot combine a structure search that retrieved compound records with a structure search that retrieved reaction records. In other words, you cannot combine reaction and compound searches.
Combine Structure Searches with Bibliographic Searches
When you combine a set created from a structure search with a set created from a search for bibliographic information in any database, the result of the set combination will be a number of article records.
Also, note that if you use AND to combine a set created from a search of the Science Citation Index with a set created from a search of Index Chemicus and/or Current Chemical Reactions, there may be no intersection between the sets if the timespan for each search is the current week or the last 2 or 4 weeks. If you want to limit results to the most current week or the last 2 or 4 weeks, go to the More Settings section of the search page, select all five databases, and then perform the search.
Set Combination Examples
#1 AND #2
Finds all records that appear in both set #1 and set #2.
#2 OR #3
Finds all records that are in set #2 and all records that are in set #3, including records common to both sets.
#1 AND #2 AND #4 AND #6
Finds all records that are common to all sets (#1, #2, #4, and #6).
Save History / Create Alert (Coming Soon*)
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.

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.
About SAME and Saved Searches
When you open a search history file created from a previous version of the product, your search may yield more results if you had used the SAME operator in your query. In the current version, the SAME operator works exactly like AND in most fields (such as the Topic and Title fields).
For example, the search query:
TS=Bird Migration SAME TS=South America*
Is automatically translated in the current version of the product into:
TS=Bird Migration AND TS=South America*
and produces a larger set of search results than the original query.
When opening a saved search history file from a previous version of the product, consider revising your query if you had used the SAME operator in the query.
Note: The exception to the rule discussed, here, is the Address field where SAME operator rules still apply.
Saving Search Queries
You can save up to 40 search sets from the Search History table. If the table contains more than 40 sets, then a message appears above the 40th row indicating that the sets below this point can be saved, but those at row 41 and above cannot be saved.
Combining Sets from ...
You are able to combine search sets created from any of the following functions within the product database.
