java - Lucene Search with Unicode Characters -

-

I have indexed a database of some texts and database texts are of Unicode encoding. When I search an English term with Lucene Search, everything goes fine. But when I use a non-English queries like: "تو" It gives me the following exception:

exception in thread "main" org.apache.lucene.queryParser.ParseException: not parse can do ' ?? ':' 'or'? 'Org.apache.lucene.queryParser.ParseException: org.apache.lucene.queryParser.QueryParser.parse on Search.main (QueryParser.java:187) as a result of the first character in WildcardQuery on (Search.java:151) Not allowed: '' or '?' First org.apache.lucene.queryParser.QueryParser.getWildcardQuery (QueryParser.java:923) on org.apache.lucene.queryParser.QueryParser.Term (QueryParser.java:1347) on org.apache allowed as character WildcardQuery is not. lucene.queryParser.QueryParser.Clause (QueryParser.java:1250) org.apache.lucene.queryParser.QueryParser.Query (QueryParser.java:1178) on org.apache.lucene.queryParser.QueryParser.TopLevelQuery (on QueryParser.java: 1167) org.apache.lucene.queryParser.QueryParser.parse (QueryParser.java:182) ... more 1

what should I do?

Thank you

here two points -.

  • encoding of what is sure (* .java) your srouce file that UTF8
  • is other than the default encoding UTF8 Java is expected to show some . Make sure that you specify the encoding like: () New FileInputStream (filename, "UTF-8")

    InputStreamReader; `

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
