RegEx: text that contains any match letter in sequence -
is possible have regex search person's name. if enter 'fb' match word 'foobar'?
yes can match letter in sequence using .*
before words.
so,in case .*f.*b
.*
cause lot of backtracking in case have more 2 words , if there multiple such words.you can instead use .*?
match lazily , avoid backtracking
