Attempting to match the entire sentence of a document containing certain words even if the sentence spans multiple lines.
My current attempts only capture the sentence if it does not span to the next lines.
^.*\b(dog|cat|bird)\b.*\.
Using ECMAScript.
When no abbreviations in the input are expected use
/\b[^?!.]*?\b(dog|cat|bird)\b[^?!.]*[.?!]/gi
See regex proof.
