getting indexed correctly.

Key: SOLR-2346
URL: https://issues.apache.org/jira/browse/SOLR-2346
Project: Solr
Issue Type: Bug
Components: contrib - Solr Cell (Tika extraction)
Affects Versions: 1.4.1
Environment: Solr 1.4.1, Packaged Jetty as servlet container, Windows
XP SP1, Machine is booted in Japanese Locale.
Reporter: Prasad Deshpande
Priority: Critical
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.
