Description
It's not simply being ignored. It seems that expressions with an
even number of characters work correctly, while those with an odd
length fail to match. Without the /i modifier, all tested
expressions have been correct.
var mystring = 'Add to Address Book';
// with /i modifier
Ti.API.info(mystring.search(/s/i)); // -1 (incorrect) (string length: odd)
Ti.API.info(mystring.search(/ss/i)); // 12 (correct) (string length: even)
Ti.API.info(mystring.search(/ess/i)); // -1 (incorrect) (string length: odd)
Ti.API.info(mystring.search(/ress/i)); // 10 (correct) (string length: even)
Ti.API.info(mystring.search(/dress/i)); // -1 (incorrect) (string length: odd)
Ti.API.info(mystring.search(/ddress/i)); // 8 (correct) (string length: even)
Ti.API.info(mystring.search(/address/i)); // -1 (incorrect) (string length: odd)
Ti.API.info(mystring.search(/address /i)); // 7 (correct) (string length: even)
// no modifier
Ti.API.info(mystring.search(/address/)); // -1 (correct) (both cases correct here)
Ti.API.info(mystring.search(/ddress/)); // 8 (correct)
Was actually a duplicate of another bug (with the same sample code!) at some point. I remember fixing it.
Tested against 1.6.0 RC1, confirmed.
