For "words" read 'searchable terms'.

Which would include strings of digits; proper nouns; and in a generic solution, any language.

For testing, I'm currently using split /[^A-Za-z0-9.'+-]+/, $line; but ultimately that should be configurable.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
