Answers to Questions (FAQ)

What is a word search with regular expression? (Definition)

The search for words by regular expression (or regex) is a method capable of going through an entire dictionary of words, and of checking if these correspond to the set accepted by the regex.

A regular expression is a tool which describes from a pattern (a character string written according to a precise syntax) a whole set of possible character strings/word.

It is then possible to search for words with complex criteria (length, pattern, repetition, etc.). The knowlegde of the syntax of regular expressions (regexp) is mandatory.
