[jira] Commented: (LUCENE-1817) it is impossible to use a custom
dictionary for SmartChineseAnalyzer
[ https://issues.apache.org/jira/browse/LUCENE-1817?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747963#action_12747963 ]
Robert Muir commented on LUCENE-1817:
-------------------------------------
I am looking at this today. One thing about this code that should also be corrected ASAP is that if you have a custom dictionary directory in .DCT format, the load() method will actually call save()
This will create a corresponding .MEM file in the same directory after loading the dictionary in DCT format.
I really do not think load() methods should be creating or writing to files.

> Key: LUCENE-1817
> URL: https://issues.apache.org/jira/browse/LUCENE-1817
> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/analyzers
> Reporter: Robert Muir
> Priority: Minor
>
> 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...
