java - Getting the Vector Space Model (tf-idf) from a query on a lucene index -

-

I need to get the vector space model (with TF-IDF load) from the result of a Lucene query, and khichadi The figure of the language is how to do it seems that it should be simple, and at this level, maybe one of you might point me in the right direction.

I am trying to understand how to do this for a good time, and either I did not understand that the stuff I have read now (more than needed), or solution The special issue has not been posted. I tried to compute myself directly with the VSM query results, but my solution has a disgusting complexity.

EDIT: For someone else who is stumbling on it, what can I get by indexReader.getTermFreqVector (string field, int.docid) method

Unfortunately This does not work for me because the index I am working on has not stored the word of the frequency vector, so I think I am still looking for more help on this!

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).
