While processing a search request using full text search in Azure, which key component would you use for matching document scores based on inverted indexes. 

Answer options:

A.Query Parsers
B.Search Engine
C.Index
D.Analyzers

Correct Answer: B
Option A is incorrect because the query parsers are used to send query structure to the search engine in the initial phase of query processing. They separate query terms from query operators before creating the query structure. 
Option B is correct because the search engine is used to retrieve and rank the scores based on relevance.
Option C is incorrect because the index (inverted) is the storage structure that stores and maintains a sorted list of the terms extracted from search documents. It also maps each search term to the document list where it is maintained.
Option D is incorrect because the analyzers are used to process strings during query execution such as removal of non-essential words or converting text from uppercase to lowercase.
