Search Rules in Derwent Innovations Index

When searching the Derwent Innovations Index database in the current version of Web of Knowledge, please continue to use the same search rules that you used in the previous version of Derwent Innovations Index.


The current version of the Derwent Innovations Index uses a different search engine from the search engine that we use in Web of Science and the other product databases within Web of Knowledge. Therefore, the search rules differ.

For example, in Derwent Innovations Index:

  • You cannot use left-hand truncation in a search query including Topic and Title searches.

  • You cannot use stopwords in a search query includeing Topic and Title searches. A search for Vitamin D will also find Vitamin A, Vitamin B, Vitamin C, and so on.

  • You cannot create search queries using the NEAR/n operator. For example, battery NEAR/15 lithium is not a valid search.


The Derwent Innovations Index is integrated with the All Databases function, and therefore, searchable when you search the All Databases function.

The Lemmatization feature is not available in the current version of the Derwent Innovations Index.

Save As My Defaults

The product allows you to save your Timespan and Database settings. These settings are found under the Current Limits heading on any Search page.

You can save these settings so that they are available each time you begin a search session. For example, you can set your timespan settings to search the Latest 5 Years. Each time you begin a new session, the product remembers this setting and only searches for records added to the product within the last 5 years.

You must be a registered user and you must sign in to save your search settings.

  1. Select the desired timespan and/or databases that you want to include in future searches.

  2. If you have not signed in, then click the sign in or register link that appears to the right of the Current Limits label to sign in or register.

  3. Click the Save as My Defaults button. The next time you sign into a new session, the product remembers your settings so you can immediately begin your research.


Interface Language

The interface language that you select determines the language of the on-screen instructions and help information. Consequently, search queries must always be in English. The results of your search are always in English.

See Selecting an Inteface Language for more information.



Do not use field tags in Search fields. For example, trying to use TS= in the Topic field to perform a Topic search will not work.

The use of field tags is not supported and will cause unpredictable retrieval of results. If you wish to use field tags in your search, go to the Advanced Search page where field tags are allowed.


Search Operator Precedence

If you use different operators in your search, the search is processed according to this order of precedence:

  1. SAME
  2. NOT
  3. AND
  4. OR
