In this part 1, the search engine searches for the occurrence of words in the content. Part 2 is slightly modified such that when we upload the content, the number of occurrences of each word is stored in the link table. The search engine then ranks with the number of occurrences of each word in the document. For example, if the word ‘paging’ occurred 11 times and ‘programs’ occurred 21 times, then the rank for the document is 11 + 12 = 23.
