Spelling correction is the identification of misspelled terms and the generation of replacements with their likely conventional spellings.
- How it is used
- Improves search relevance by generating domain-specific replacements for misspelled query terms.
- How deep it goes
- Traces an implementation from query collection through tokenization, quantiles, candidate matching, and edit-distance filtering.
- Examples
- Uses product queries such as moden, latop, tosheba, and multiterm variants including hp toucpad.
- What you can do after
- Build it from scratch with SQL, Python, NLTK, pandas, quantiles, and edit-distance rules.

A spelling suggestion is a proposed correctly spelled word corresponding to a misspelled input.
- How it is used
- Organizes a spell-checking task into input, candidate processing, and user-facing output.
- How deep it goes
- Explains functional decomposition and candidate filtering, but defers detailed correction algorithms.
- Examples
- Uses sucessful, thourough, acceptible, and carf with an English word-list file.
- What you can do after
- Build it from scratch as a Python program that reads a word list and prints possible corrections.
