----------------------------------------
One more small query. We have requirement where we have to add new words to our
dictionary quite frequently. So multiple threads may concurrently call index
dictionary. This will cause problems as each call to indexDictionary will
create a new IndexWriter. So is it possible to make indexDictionary function
synchronized? Like this
public synchronized void indexDictionary(Dictionary dict) throws IOException {

> SpellChecker does not work properly on calling indexDictionary after

> Key: LUCENE-1152
> URL: https://issues.apache.org/jira/browse/LUCENE-1152
> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/*
> Affects Versions: 2.3
> Reporter: Naveen Belkale
> Attachments: spellchecker.diff

>
> We have to call clearIndex and indexDictionary to rebuild dictionary from
> fresh. The call to SpellChecker clearIndex() function does not reset the
> searcher. Hence, when we call indexDictionary after that, many entries that
> are already in the stale searcher will not be indexed.
> Also, I see that IndexReader reader is used for the sole purpose of obtaining
> the docFreq of a given term in exist() function. This functionality can also
> be obtained by using just the searcher by calling searcher.docFreq. Thus, can
> we get away completely with reader and code associated with it like
> if (IndexReader.isLocked(spellIndex)){
> IndexReader.unlock(spellIndex);
> }
> and the reader related code in finalize?
