Hello Marius - thank you for the detailed reply.
My goal is (2) - to find all documents with a .7z attachment, where those attachments
include file(s) containing "foo". If I read your email correctly, Tika 1.6 (5)
is root cause for my failure to search successfully for text within the files contained in
a .7z attachment. I am successful with my search when using a .zip file as the attachment
- so we will instruct wiki users to avoid .7z attachments.
Yes, at least until we upgrade to Tika 1.7.
FTR we’re now using Tika 1.7 in the latest versions of XWiki.
Thanks
