In Web of Science there are 5 search types, i.e. Documents, Cited Reference, Advanced, Author and Structure Search:
Smart Search: This is a new search system which allows you to use natural language in inputting your query. On 31st July 2025, Smart Search replaced Documents Search as the default setting on the landing page in Web of Science. Users can toggle Smart Search to the off position, to revert to the classic Web of Science 5 search type options (as listed above).
In Web of Science, the default search option is ‘Documents' and the search range is 'All Fields', we recommend selecting 'Topic' for more accurate results and efficient search. Note: A search by Topic will search in the title, abstract and keyword fields.
Enter your search term(s) in the search box(es) and ensure 'Topic' is selected in the drop-down menu.
A link to search tips can be found to the right of the search button. To add search lines click on +Add row.
Combine search terms using search operators AND and OR. These may be typed in the search boxes or selected from the drop-down menus.
When you have entered all your search terms, click on the Search button.

With Smart Search you may use natural language or specific search terms in your query, users who enter search terms do not need to enter Boolean terms, as the system will generate a traditional Boolean search (AND, OR, NOT) on your behalf. The system will also perform a semantic search (using synonyms or similar terms to the ones you have used already).
These two searches are combined to give you a set of relevant results and researchers.From the result set, you can choose to see only the 'Boolean' or 'Semantic' searches and their respective results. Smart search performs two types of searches: Document Search and Author Search.
