Java Regex looking a combination of words in any order

问题

I'm looking for a way to find two or more words in a sentence that might come in any order. For example I might look for the words "NCAA" and "Basketball" in a sentence that says NCAA Indiana Vs. Purdue Basketball" or it might say "Indiana Vs. Purdue Basketball NCAA". How would I write the regex for the words showing in any order and any location in the string?

回答1:

You can use lookahead:

(?=.*?NCAA)(?=.*?Basketball)

Or else use alternation:

NCAA.*?Basketball|Basketball.*?NCAA
