Java Regex：匹配字符串包含许多文本中的任意两个

Question

Want to match a string containing

(text1 or text2) and ( text3 or text4) and (text5) and (any of two among text6,text7,text8 and text9)

So far I have tried

^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5).*$

which matches a string contains (text1 or text2) and ( text3 or text4) and (text5)

How to write a single pattern which fulfills my need.

**PS:**I don't want to divide the last part(any of two among text6,text7,text8 and text9) and write regex like

(^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5)(?=.*text6)(?=.*text7).*$)|(^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5)(?=.*text6)(?=.*text8).*$)|(^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5)(?=.*text6)(?=.*text9).*$)|(^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5)(?=.*text7)(?=.*text8).*$)|(^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5)(?=.*text7)(?=.*text9).\*$)|(^(?=.*(text1|text2))(?=.*(text3|text4))(?=.*text5)(?=.*text8)(?=.*text9).*$)

Since i don't know how many texts i gonna have in my last part.

Any suggestions would be highly appreciated.

Just change your regex like below.

^(?=.*(text[12]))(?=.*(text[34]))(?=.*text5)(?=.*(text[6789]))(?=.*(?:(?!\3)text[6789])).*$

Java regex would be,

"^(?=.*(text[12]))(?=.*(text[34]))(?=.*text5)(?=.*(text[6789]))(?=.*(?:(?!\\3)text[6789])).*$"

DEMO

(?=.*(text[6789]))(?=.*(?:(?!\\3)text[6789])) Asserts that there must be be two text[6789] or text[6789] but the text strings must not be repeated.
