Question

Does anyone know of a way to merge/combine the lists of recent changes from multiple webs into one big list of recent changes that disregards webs and simply sorts them by the last modified date?

I know that you can do such a list that will include, say, the top 10 recent changes from each web. However, if you specify 5 webs the comprehensive list will be 50 topics long.

Now, what I'd like to do is provide a comprehensive top 10 recent updates list regardless of web. I want to still specify 5 webs from which the search is run against, but at any given time one or more webs may not even have any topics listed.

Currently, the only way I can configure my top 10 recent updates list is to specify the 5 webs and then set the limit of topics to 2. The problem with this is that I may have newer recent changes to 4 topics in my Training web than I do to any topics in my Manuals web. But, because of the limits of the search, I'll see the older recent changes to two topics in the Manuals web and miss out on two of the four topics in the Training web.

The topics I've seen here on TWiki.org described this issue as being unresolved, but date back to 2003 and mention that this functionality might be addressed in a rewrite of Search.pm. I haven't been able to determine whether this happened (in Search.pm or any other portion of TWiki).

There's no way to do it in TWikiRelease04Sep2004 that I know of.

With DakarRelease / TWikiRelease04x00x02 there's a date parameter for search that can take a time interval.

The closest you can get with Cairo is WebChangesForAllWebs, which sorts changes by date across all webs. But it has the issue described that it operates on a number of topics per web instead of date.

Idea: In Cairo, you could try to feed the result into a SpreadSheetPlugin variable as a list element. Each list element would contain just "$isodate $web/$topic", which is sortable by date. After the search, you can sort the list, trim it, format it and then print it out.
