Google's search results will give us a 918,000 documents. Pay attention to the search results for words in boldface type. These words Google thinks match your search. When prompted 'abstracts' Google ignores the word 'abstract', and considers only the words 'abstracts'. Send a Google search query 'summary'. The result will be completely different. You can not even compare top positions of the search result. Look at the number of documents found – only 327,000, almost 3 times less than the negotiated 'abstracts'.
