Question

We have been using TWiki for more than 6 months now. We have 6 form templates and around 500 forms filled out. We query these forms and display their results using FormattedSearch.

All of a sudden, the SEARCH stopped working. There are no results returned for any form data. Last week, we managed to get data displayed on a page "Refresh" at times. Now, "Refresh" also does not work.

Is there a limit to the number of forms that TWiki metadata can support? Has anyone else experienced this problem?

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

What version of TWiki are you running? What OS is the server running on? Quite older versions of TWiki had a limit on the number of topics that could be searched in a web. This limit is based on the shell command lenght limitation of the OS when search calls the external grep.

Peter,

Thanks for your reply!

It could very well be due to the fact that we have an older version running. I do not have admin access to the server.I will check with the admin group and update this topic with what I find.

just look at your TWiki.WebHome; it should have version information at the bottom of the page.

Will,

Our installation does not have this information on the WebHome page. But I looked in the TWikiDocumentation topic and found the WIKIVERSION to be 01 Feb 2003

I guess we will need an upgrade to resolve this issue.

Thanks!

Upgarde is ceratinly the best option. We will soon release DakarRelease with many new features.

I think it could do a temporary workaround without and upgrade. Create a wrapper script for grep; set TWiki.cfg to point to the wrapper; the wrapper uses xargs that calls grep.

Or you could hand-patch lib/TWiki/Search.pm based on the one in TWikiRelease04Sep2004. Look at line 212 ff for a fix of ArgumentListIsTooLongForSearch.
