Which of the following is a common technique used for implementing full-text search in databases?

  • Regular Expressions
  • Binary Search
  • Inverted Index
  • Depth-First Search
A common technique for implementing full-text search in databases is the use of an inverted index. This index stores a list of words or terms along with the locations where they appear in the documents, making it efficient for searching large volumes of text. Regular expressions, binary search, and depth-first search are not typically used for full-text search in databases.
