Use this tag with Regex that are aware of Greedy, Reluctant and Possessive. If it is just Greedy and Nongreedy then consider using the tag non-greedy.
Reluctant is used more often when the Regex is capable of doing the following three
- Greedy
- Reluctant (AKA Nongreedy)
- Possessive
When the Regex is capable of doing just
- Greedy
- Nongreedy
then Nongreedy tends to be used instead of Reluctant
