------------------------------------------
I am interested in working on adding the feature to allow use customized dictionary in text
file, not DCT file.
I have a couple of questions before trying on it.
In the package, I only saw .mem file. Where should I download .dct file and how to convert
from text file to dct file?
> it is impossible to use a custom dictionary for SmartChineseAnalyzer

> it is not possible to use a custom dictionary, even though there is a lot of code and
javadocs to allow this.
> This is because the custom dictionary is only loaded if it cannot load the built-in one
(which is of course, in the jar file and should load)
> {code}
> public synchronized static WordDictionary getInstance() {
> if (singleInstance == null) {
> singleInstance = new WordDictionary(); // load from jar file
> try {
> singleInstance.load();
> } catch (IOException e) { // loading from jar file must fail before it checks the
AnalyzerProfile (where this can be configured)
> String wordDictRoot = AnalyzerProfile.ANALYSIS_DATA_DIR;
> singleInstance.load(wordDictRoot);
> } catch (ClassNotFoundException e) {
> throw new RuntimeException(e);
> }
> }
> return singleInstance;
> }
> {code}
> I think we should either correct this, document this, or disable custom dictionary support...
