Subject Re: Extracting contents of zipped files with Tika and Solr 1.4.1
Date Mon, 11 Apr 2011 02:35:26 GMT
Hi Gary,

I have been experiencing the same problem... Unable to extract content from
archive file formats.  I just tried again with a clean install of Solr 3.1.0
(using Tika 0.8) and continue to experience the same results.  Did you have
any success with this problem with Solr 1.4.1 or 3.1.0 ?

I'm using this curl command to send data to Solr.
curl "
http://localhost:8080/solr/update/extract?literal.id=doc1&fmap.content=attr_content&commit=true"
-H "application/octet-stream" -F  "myfile=@data.zip"

No problem extracting single rich text documents, but archive files only
result in the file names within the archive being indexed. Am I missing
something else in my configuration? Solr doesn't seem to be unpacking the
archive files. Based on the email chain associated with your first message,
some people have been able to get this functionality to work as desired.
