To understand this better, we take another example of the
asbestos sheets that are brought to use in chemistry
laboratories as an apparatus, as a building material to
safeguard from fire (fire resilience) and in electric heaters for
cooking or keeping the room warm during winters. We need
to make sure of the intent of the user if he wishes to search for
information that would list the use of asbestos sheets or that a
catalog that would help a user to find the rates at which the
asbestos sheets are available in varied quantities.
