Abstract:
How to pose questions to Web4Health.

Question:

Can I use "OR" and "AND" in questions in Web4Health.

Answer:

The natural-language question-answering systems used in Web4Health does not use boolean operator words like "OR" and "AND". You should write natural questions. You can of course use "or" and "and" as part of natural language questions.

If you want to perform Boolean search, go to our advanced search page.
