It depends what you mean by "search attachments that are 7-Zip .7z archives": (1) Give me all the documents that have an attachment of mime type application/x-7z-compressed (2) Give me all the documents that have a 7-Zip archive attached that includes a file that contains the word "foo" If you use Solr, the default search engine for XWiki 6.2.4, then the code that is responsible for indexing the attachments is AttachmentSolrMetadataExtractor [1]. This is a component so it can be overridden as per [2]. The current implementation uses Tika [3] to: (1) detect the mime type of the attachment (2) extract indexable content from the attachment (whatever its mime type may be) For (1) Tika supports detecting the 7-Zip mime type since version 1.2 [4]. For (2) judging by [5] it seems Tika also supports reading 7-ZIP archives but there were some issues in 1.6 that have been fixed in 1.7. We are currently using Tika 1.6 in XWiki. We should probably upgrade. Hope this helps, Marius [1] https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwik...

Hello - is it possible to enable searching of additional filetypes within XWiki 6.2.4? Specifically I would like to be able to search attachments that are 7-Zip .7z archives. It looks to me as though the underlying library (Commons Compress) supports this filetype, but I am a new XWiki user and non-java programmer so I may be assuming too much.

Thanks in advance for your thoughts on this -

Garth Arnold
