How are plural nouns handled?

Plurals are not automatically included in any search; they need to be explicitly included by the user:

• Keyword Tool: When finding similar terms for a noun, say investment, the Keyword Tool finds similar terms for investment only; it does not assume the input implies plural too. To include the plural form, please enter both investment and investments.

• Risk Tool: Similarly, in the Risk Tool, searching for investment, will also not find its plural form. To include its plural, please enter both investment and investments; or use a wildcard operator, e.g. investment?.
