You are tasked with finding a specific word in a large document. Discuss whether linear search would be an appropriate approach and propose alternative strategies if necessary.

Linear search may not be the most appropriate approach for searching a specific word in a large document due to its time complexity. Binary search, hashing, or indexing could be more suitable alternatives. Binary search is efficient for sorted data, hashing provides constant time complexity on average, and indexing can expedite search operations by creating a mapping between words and their locations.
