Omnibox Or Statement
Is there something I need to do to make OR clause get recognized?
The boolean operators should be written in uppercase for Coveo Enterprise Search to recognize them. Lowercase operators are treated as words by default (see Boolean Operators).
Note: The option to "recognize Boolean operators independently of the casing" in the documentation applies only to the Coveo .Net Front-End product
enableLowercaseOperators if used in the initialization options and
data-enable-lowercase-operators if used in the markup (see enableLowercaseOperators).
