SpellChecker in use with composite query

Hi
I have been playing around with the SpellChecker class and so far it looks
really good. While developing a testcase to show it working I came across a
couple of issues which I have resolved but I'm not certain if this is the
correct approach. I would therefore be grateful if anyone could tell me
whether it is correct or I should try something else.

1) Multple Indexes:
I have multiple indexes which store different documents based on certain
subject matter. So inorder to perform the spellchecking against all indexes
I did something like this:

IndexReader spellReader = IndexReader.open(fsDirectory1);

IndexReader spellReader2 = IndexReader.open(fsDirectory2);

MultiReader multiReader = new MultiReader(new IndexReader[]
{spellReader,spellReader2});

LuceneDictionary luceneDictionary = new LuceneDictionary(multiReader,
"content");

Directory spellDirectory = FSDirectory.getDirectory(<single index for
spellcheck);

SpellChecker spellChecker = new SpellChecker(spellDirectory);

spellChecker.indexDictionary(luceneDictionary);


Is this an acceptable approach or should there be a spellcheck index for
each seperate document index?



2) Composite query e.g. Luciene OR doqument

Inorder to handle the above i did the following:


QueryParser queryParser = new AnalyzingQueryParser("content",analyzer);

String input = "luciene OR doqument";

Query query = queryParser.parse(input);

String input2 = query.toString("content");

String[] splitString = input2.split(" ");


For each of the string in the array i performed the suggestSimilar(..).


Is this the most appropriate way of doing this?



Any help would be appreciated.


Cheers
