Purpose of Content, Title and Keyword in semantic ranking

Question

I am new to semantic search/semantic ranking. I might also be incorrectly using the words. I have few questions to understand the concept of semantic ranking, if someone could help.

1. Are Semantic search and Semantic ranking same?
2. In Azure AI search, when creating a search index which does semantic ranking, the configuration requires three fields - title, content and keyword. What is their purpose and how does semantic ranker uses them ? https://learn.microsoft.com/en-us/python/api/azure-search-documents/azure.search.documents.indexes.models.prioritizedfields?view=azure-python-preview

Eventually, I am trying to get answer to this question in which the search didn't return the right answer - https://learn.microsoft.com/en-us/python/api/azure-search-documents/azure.search.documents.indexes.models.prioritizedfields?view=azure-python-preview

Answer 1

Semantic ranking was formerly named "semantic search". See https://learn.microsoft.com/en-us/azure/search/whats-new#:~:text=Semantic%20ranking%2C%20generally,for%20production%20workloads.

As part of the General Availability announcement, the product was renamed (likely to clarify the feature performs reranking of results)

The other comment has linked the correct page that explains the purpose of the three fields title, content and keyword. (https://learn.microsoft.com/en-us/azure/search/semantic-how-to-query-request?tabs=portal%2Cportal-query#2---create-a-semantic-configuration)
