Bug: Grave Inline Search Error when Web Size grows very big

When more than a thousand Topics are in a Web, the WebChanges, WebIndex and all Inline Search does not yield ANY results! The Apache error log file states: sh: /usr/bin/egrep: arg list too long

any workarounds despite reducing the arg list ie topics of the web by deleting ? is there an official maximum of Topics in a Web ?

Test case

TWiki plugins:  
Server OS: AIX
Web server: IBM HTTP Server 1.3.6
Perl version: v5.6.0 built for aix

Follow up

First of all, congratulations on having a successful TWiki smile ... See Google:twiki+xargs (ArgumentListTooLong) for a fairly simple solution to this. Should really go into the TWiki core as a commented-out line in TWiki.cfg, ready to be uncommented when sites hit this limit (which varies depending on the Unix version by the way).

Fix record

This is now fixed, is in TWikiAlphaRelease and at TWiki.org. This is part of working on SearchTopicNameAndTopicText, ExcludeWebTopicsFromSearch, SearchWithNoPipe, ArgumentListIsTooLongForSearch, SearchWebHasTooManyParameters, SiteMapIsSlow.

How: The Search module first gets all topics in a web, then calls the external grep with sets of up to 512 files at a time.
