Problem indexing documents

After successfully installing KnowledgeTree version 3.6.1 on a RHEL 5 server, I uploaded several text files and an .xlsx file. I noticed that none of the documents were being indexed, so I wasn’t able to search within the documents themselves. When I checked the “Document Indexer and External Resource Dependency Status” under “Searching and Indexing”, I noticed there was an error message regarding OpenOffice.org not being installed. So after I installed that, the message went away. I then rescheduled all documents to be re-indexed. However, the documents are staying in the queue and aren’t being indexed at all. I even went in the database and checked the table “index_files” and noticed that both “processdate” and “status_msg” were null. Any suggestions as to what I should do next?

Thanks,
Brian

Hi,

I’m not a KnowledgeTree expert but I think that it is possible that the application requires to start OpenOffice as server. Try to start OpenOffice using the following command:

$ soffice -nofirststartwizard -nologo -headless -accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager

I hope it helps.

I was able to start the OOo server successfully (checked that process was running by executing “ps -ef | grep soffice”) and rescheduled the documents to be indexed. However, I am still not seeing any indexing activity at all. There is still one message under “Document Indexer and External Resource Dependency Status”:

The following extractors are not available and may affect indexing of certain document types:
PostScript Text Extractor

• Message: Cannot locate binary for PostScript Text Extractor (pstotext).
• no help for PSExtractor
• Affected file formats: ps

I don’t have any .ps files, though, so I don’t think should be affecting anything. I also checked the respective log file under $KT_HOME/apps/knowledgetree/htdocs/var/log but nothing had been written to it.

It is possible that the PS is used as an intermediate format between other non-cross-platform ones … thus, it becomes a must like the EMF on windoze …

I have installed the OSX version and am having the same type of problems – all my documents are sitting in the queue and nothing is being indexed. No errors or issues in the logs… see attached screen shot of the Indexer Stats.

I’m experiencing the same issue with an Ubuntu install of 3.6.1 – all my documents are sitting in the queue and nothing is being indexed. There are no errors in the logs that I can see. There are warnings about missing apps, or non-running apps in the administration screens relating to searching and indexing.

Has anyone figured this issue out?

Hi,

Check the following:

$ ./ctlscript.sh status

The Lucene server should be running. If not try to start it “./ctlscript.sh start lucene”.

Then go to the following url:

http://YOUR_HOST:YOUR_PORT/knowledgetree/search2/documentProcessor/bin/documentProcessor.php

Check now the indexer stats. To run the document processor periodically you should to create a cron task. You can find more info at http://knowledgetree.org/Scheduler.

I hope this helps you.
