Methinks the index, being a database, needs only to be corrected on a 
parhaps nightly basis. The serverside action can very well identify pages 
that are changed since the last correction, and only rebuild the data of 
that page.

Now and then, a hand-started total new index database could be done.

"Typically"? [as in: "typically programmers are very inefficient"?]

What is "run via", do you mean "initialized by" or "run on" a web page?

I do, this is a Javascript NG, so presumably  the audience is well versed 
in this language.

Why? Does it just make sense or does it make mor sense than to do this on 
the server?

If the client would index the text-result of the pages loaded to index 
that, it would be sensible, but forgoing selected pages that have changed,
and not being able to interact efficiently with the database on the server 
would not.

Depending on size and dynamics of a site, I would vote for serverside 
updating.
