Shall we take a bold decision?

1. Nick's request could be addressed by adding an example that addresses
non-alphanumeric.  (e.g. to find all cases of word but not "word").
Other examples on the page give the template for how to present the example. 

If someone would provide the text, then I would add it to the regex help page.

(the downside with this solution is that the relevant regex operators are not
mentioned on the page. Would be relevant to add them -- but the ICU explanation
is incomprehensible, unless you know already know regex -- in which case a link
to the relevant "manual" might be better -- and two relevant links are already
available.)

2. Maybe better to add a tip on:  "Using Regular Expressions in Text Searches"
https://help.libreoffice.org/7.1/en-US/text/swriter/guide/search_regexp.html
(isn't that where a user might search?)  And instead of explaining how, just
give a short tip that indicates possibilities (which the user then has to RTM).
For example:  

To search for (Nick's type of case) here, then use (relevant syntax).

or

Use Positive Lookahead, Negative Lookahead, Positive Lookbehind, and Negative
Lookbehind to (short explanation of what they are good for).  See (link to ICU
manual) for relevant operators.

3.  And if 1 and 2 are rejected, then I propose this bug be resolved as NAB or
WF.
