也许你应该尝试一些拼写变化:
information documentation » international documentation, information presentation, information documents
documentation program » documentation programme, documentation programming, documentation problems
program definitions » problem definitions, problems definitions, program descriptions
concepts citrus » concepts cited, concepts critiques, concepts circuits
concepts chris » concepts cases, concepts care, concepts carol

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

• Performing a fuzzy search may retrieve terms with similar spellings: information documentation program definitions ((concepts citrus) OR (concepts chris))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information documentation program definitions ((concepts citrus) OR (concepts chris))".
• Adding a wildcard symbol may retrieve word variants: information documentation program definitions ((concepts citrus) OR (concepts chris))*.
