Perhaps you should try some spelling variations:
communication context » communication contexts, communication content, communicative context
elicitation from » elicitation _
exceptions from » perceptions from
exception from » perception from, reception from, exception flow
context based » content based

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication context based ((((exception from) or (exceptions from))) or (elicitation from)) river~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication context based ((((exception from) OR (exceptions from))) OR (elicitation from)) river.
• Adding a wildcard symbol may retrieve word variants: communication context based ((((exception from) or (exceptions from))) or (elicitation from)) river*.
