Step-by-step explanation:
The subject of this question is Boolean operators in the context of keyword searching. Specifically, the question is asking about the different types of keyword matches in a search query.a) Exact match: This refers to a keyword search that only returns results that include the exact keyword phrase. For example, if the search query is '+women's +hats', an exact match would only show results that include both the words 'women's' and 'hats'.b) Broad match: This refers to a keyword search that includes variations of the keywords or related terms. For example, a broad match search for 'hats for women' could include results for 'hats for ladies' or 'women's headwear'.
c) Negative match: This refers to a keyword search that excludes certain keywords or phrases. For example, negative match search for 'hats -women' would exclude any results that include the word 'women'.d) Phrase match: This refers to a keyword search that returns results that include the exact phrase, even if there are additional words before or after the phrase. For example, a phrase match search for 'hats for women' could include results for 'cute hats for women' or 'cheap hats for women.
