Talvez debería tentar con algunhas variantes ortográficas:
information sources » information resources, information services, information sciences
small dimensions » small dimension, skull dimensions, all dimensions
array formulas » area formulas, harrop formulas, array formats
sources small » sources sally, sources sample, sources cell
array string » array strong, arrays strings, array sharing

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

• Performing a fuzzy search may retrieve terms with similar spellings: information sources small dimensions ((array format) or (((array formulas) or (array string))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information sources small dimensions ((array format) OR (((array formulas) OR (array string)))).
• Adding a wildcard symbol may retrieve word variants: information sources small dimensions ((array format) or (((array formulas) or (array string))))*.
