[jira] [Updated] (SOLR-2346) Non UTF-8 Text files having other than
english texts(Japanese/Hebrew) are no getting indexed correctly.
[ https://issues.apache.org/jira/browse/SOLR-2346?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Koji Sekiguchi updated SOLR-2346:
---------------------------------
Attachment: SOLR-2346.patch
New patch attached. I updated for current trunk and getCharsetFromContentType() method to remove unnecessary strings after the charset value.
I think this is ready to go.

> I am able to successfully index/search non-Engilsh files (like Hebrew, Japanese) which was encoded in UTF-8. However, When I tried to index data which was encoded in local encoding like Big5 for Japanese I could not see the desired results. The contents after indexing looked garbled for Big5 encoded document when I searched for all indexed documents. When I index attached non utf-8 file it indexes in following way
> - <result name="response" numFound="1" start="0">
> - <doc>
> - <arr name="attr_content">
> <str>�� ������</str>
> </arr>
> - <arr name="attr_content_encoding">
> <str>Big5</str>
> </arr>
> - <arr name="attr_content_language">
> <str>zh</str>
> </arr>
> - <arr name="attr_language">
> <str>zh</str>
> </arr>
> - <arr name="attr_stream_size">
> <str>17</str>
> </arr>
> - <arr name="content_type">
> <str>text/plain</str>
> </arr>
> <str name="id">doc2</str>
> </doc>
> </result>
> </response>
> Here you said it index file in UTF8 however it seems that non UTF8 file gets indexed in Big5 encoding.
> Here I tried fetching indexed data stream in Big5 and converted in UTF8.
> String id = (String) resulDocument.getFirstValue("attr_content");
> byte[] bytearray = id.getBytes("Big5");
> String utf8String = new String(bytearray, "UTF-8");
> It does not gives expected results.
> When I index UTF-8 file it indexes like following
> - <doc>
> - <arr name="attr_content">
> <str>マイ ネットワーク</str>
> </arr>
> - <arr name="attr_content_encoding">
> <str>UTF-8</str>
> </arr>
> - <arr name="attr_stream_content_type">
> <str>text/plain</str>
> </arr>
> - <arr name="attr_stream_name">
> <str>sample_jap_unicode.txt</str>
> </arr>
> - <arr name="attr_stream_size">
> <str>28</str>
> </arr>
> - <arr name="attr_stream_source_info">
> <str>myfile</str>
> </arr>
> - <arr name="content_type">
> <str>text/plain</str>
> </arr>
> <str name="id">doc2</str>
> </doc>
> So, I can index and search UTF-8 data.
> For more reference below is the discussion with Yonik.
> Please find attached TXT file which I was using to index and search.
> curl "http://localhost:8983/solr/update/extract?literal.id=doc1&uprefix=attr_&fmap.content=attr_content&fmap.div=foo_t&boost.foo_t=3&commit=true&charset=utf-8" -F "myfile=@sample_jap_non_UTF-8"
> One problem is that you are giving big5 encoded text to Solr and saying that it's UTF8.
> Here's one way to actually tell solr what the encoding of the text you are sending is:
> curl "http://localhost:8983/solr/update/extract?literal.id=doc1&uprefix=attr_&fmap.content=attr_content&fmap.div=foo_t&boost.foo_t=3&commit=true" --data-binary @sample_jap_non_UTF-8.txt -H 'Content-type:text/plain; charset=big5'
> Now the problem appears that for some reason, this doesn't work...
> Could you open a JIRA issue and attach your two test files?
