How do I disable indexing of attachments

Sometimes a user can experience problems indexing large MSExcel or MSPowerPoint documents and the reindexing may cause potential Unknown Ptg warning messages that are harmless. There is already a request to Suppress these warnings from the re-indexing of unreadable documents by the POI library.

The error is usually not serious yet can sometimes cause problems when large attachments are used. So you may like to disable indexing of a particular type of document.

To do this, you need to modify the confluence\WEB-INF\classes\plugins\attachment-extractors.xml and comment out the relevant file type extractor. From Confluence 2.6, attachment-extractors.xml is packaged inside confluence-2.6.0.jar; we have instructions for Editing files within .jar archives if you're unfamiliar with the process.

The example below shows a pdfContentExtractor disabled which would cause PDF attachments not to be indexed.

Once the ContentExtractor for a file type is disabled, all files of that type become unsearchable.
