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.
dCode allows a search for words with regular expressions in the dictionary.
Example: To find a word of 4 letters starting with R or T and ending with its initial letter: ^([RT])..\1$
Example: To find a word with four consecutive vowels: [AEIOUY]{4}
dCode uses the PCRE engine (Perl Compatible Regular Expressions) and follow its standard: here (link)
Operators: ? for zero repetition or once, * for zero repetition, one or more times, + for a repeat at least once, ^ to a word beginning $ for the end of words, | for an alternative, etc. See here (link)
