I am looking for a function like strpos() with two significant differences:
Of course it has to be an efficient solution not just a loop through every needle. I have searched through this forum and there were similar questions to this one, like:
but nether of them was what I am looking for. I am using strpos just to illustrate my question better, probably something entirely different has to be used for this purpose.
I am aware of Zend_Search_Lucene and I am interested if it can be used to achieve this and how (just the general idea)?
Thanks a lot for Your help and time!

strpos in PHP is a built-in function. Its use is to find the first occurrence of a substring in a string or a string inside another string. The function returns an integer value which is the index of the first occurrence of the string.
The strpos() function finds the position of the first occurrence of a string inside another string. The stripos() function finds the position of the first occurrence of a string inside another string. 2. It is case-sensitive function.
Return Value: Returns the position of the first occurrence of a string inside another string, or FALSE if the string is not found.
You can use the PHP strpos() function to check whether a string contains a specific word or not. The strpos() function returns the position of the first occurrence of a substring in a string. If the substring is not found it returns false .
try preg match for multiple
if (preg_match('/word|word2/i', $str)) Checking for multiple strpos values
