D'oh! You found a bug (text/swriter/00/00000406.xhp#wordcount not found).
In general, every string of characters between two spaces is a word. Dashes, tabs, line breaks, and paragraph breaks are word limits, too.
Words with always visible hyphens, as in plug-in, add-on, user/config, are counted as one word each.
The words can be a mix of letters, numbers, and special characters. So the following text counts as four words: abc123 1.23 "$" http://www.example.com.
To add a custom character to be considered as the word limit, choose LibreOffice - PreferencesTools - Options - LibreOffice Writer - General and add the character into the Additional separators field.
