Searching matching email regexp anomaly

[zhuzhangli]

When I use the Searching for regular email: "[A Za - z0 - _ - 9] + @ [A Za - z0 - _ - 9] + (. [A Za - z0 - _ - 9] +) +", because in the pretreatment stage automatically increases the prefix ". * ", will lead to inaccurate regular.

Eg: "Zhangsan [email protected]", my original intention was to match "[email protected]", but actually the matching result is "Zhangsan [email protected]"

How can i deal with the problem?

Thanks~
