Search snippets: improve display

Maybe we can fold >>>>> into > (or even remove?) and trim the results ?

It's an improvement at best I would say, why the bug label?

[chibenwa]

We can discuss this.

If my mother sees that I'm pretty sure she'd say "its a bug!"

We can also trim white spaces ?

Disregard my remark during the meeting as the OpenSearch stack do prefer using text/plain to text/html for indexing. Thus the user formatted text is feeded onto the search engine and HTML extraction is avoided anyway.

Let's not change that

However the cleanup might rather be done at indexing time (so once)

Updated the PR to remove before indexing
