All database products within the Web of Science platform includes a spellchecker that checks your search queries against common spellings and their variants to determine if alternative spellings exist that would improve your search results.
If the system determines that an alternative spelling exists, a Did You Mean text box appears offering you an alternative search query. The tool checks full terms and not truncated terms or terms within quotation marks.
- Did You Mean: Topic=(suggested search terms) [NNN results]
- Did You Mean: (Topic=(suggested search terms) AND Author=(author name)) [NNN results]
When you select the Did You Mean suggestion, a new search opens and takes you to the results page. The original search and the Did You Mean search both display in the Search History.
If no results are found, and there are no Did You Mean suggestions, you will get a list search tips to help return better results.

The product uses an implicit AND operator when you enter two or more adjacent terms in most fields. For example, entering rainbow trout fish farm in the search field is equivalent to entering rainbow AND trout AND fish AND farm; both queries return the same number of results.
