Talvez debería tentar con algunhas variantes ortográficas:
information estimation » deformation estimation, information motivation, information extraction
estimation systems » estimation system, estimating systems, stimulation systems
systems report » systems recent
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 estimation systems report ((((array format) or (array string))) or (arrays using))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information estimation systems report ((((array format) OR (array string))) OR (arrays using)).
• Adding a wildcard symbol may retrieve word variants: information estimation systems report ((((array format) or (array string))) or (arrays using))*.
