java - How do I use ASCIIFoldingFilter in my Lucene app? -

-

I have a standard Lucene app that searches from an index. There are so many French words in my index and I am using ASCIfolding filters. Want to use

I have searched a lot and I do not know how to use it. The constructor takes a tokenstream object, will I call that method on the analyzer which gets the flow of the flow when you send it to the field? So what do I do? Does anyone point me to an example where a token filter is being used? Thank you.

token filters - such as ASCIIfolding filters - have a tokenstream based on them, so they are some of the analyzer main Uses the following method from: 

  public abstract TokenStream tokenStream (string field, reader reader);

As you have seen, the filters take a tokenstream as an input. They work like wrappers or more correctly, as if their input means that they increase the behavior of the token stream contained, display both their operation and the inherent input operation.

You can get an explanation. It is not directly focusing on an ASCIIfolding filter, but the same principle applies. Basically, you create a custom analyzer with something like this (the example is stripped down): 

  Expands the public class CustomAnalyzer Analyzer {// Other content left // ... public tokenstream token stream (string field name, reader reader) {tokenstream result = new standard connector (reader); Results = new standard filter (results); Result = New Lower Sense Filter (results); // etc etc ... Result = New StopFilter (Results, yourSetOfStopWords); Results = new ASCIIfolding filter (results); Return result; } // ...}

are both sub-categories of both tokenfilter and tokenerager.

Also remember that you should use the same custom analyzer in both the indexing and search or you can get the wrong result in your questions.

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).
