Search Engine (Full Text Search)

About

Full-text search is a battle between:

  • precision—returning as few irrelevant documents as possible
  • and recall—returning as many relevant documents as possible.

While matching only the exact words that the user has queried would be precise, it is not enough. We would miss out on many documents that the user would consider to be relevant. Instead, we need to spread the net wider, to also search for words that are not exactly the same as the original but are related (word stem, synonym ?)

Keywords / Search term
