 A parameter MaxEntries would be the maximum number of entries to return if @DBLookup hits multiple entries.
 
For example, I want to return the Last 5 entries in a discussion for web display, but don't want to use an embedded view (because I'm using pure HTML with <computed values> on a really fast web page), and I don't want to use x-pages because I can't achieve the same performance as I can this way, before you give me the political line about 'should be using x-pages' :)

I think it's a good idea, though I wonder about how it would pick the entries to display. Should it always be the last modified X number of entries? Or last X created? Or first/last X items by view sort order?

I think you could build the contents using XML ReadViewEntries (via AJAX, for example) and avoid using @DBLookup at all.

@1 The view sorting should be respected as is the case currently.

use ?OpenView&count=5 in an iframe. Mark the view as passthru HTML. The $$ViewTemplate does the surrounding HTML.

or use ?ReadViewEntries&count=5&Outputformat=JSON in an Ajax call

Much more efficient that the @dbLookup (where you could do @Subset(@db....;5)

iframes = code sequencing "readystate" issues. ie code must wait for data-bearing iframes to be ready. v-messy.

If you do it using AJAX and ReadViewEntries, I think you find that data retrieval is very fast.

it's very good idea for web design!

no ajax, no iframe, if need SEO optimization for my site on Domino
7) Kenneth Axi1694 (19 Feb 2012)
I don't like the idea of using @DbLookup for this. There are much more efficient ways to achieve this. I would definitly do as Stephan stated above; use the ReadViewEntries in Ajax call.
