Hi
Another thing that I was wondering is how to apply the construction of the
spell index. Where is the most appropriate place to create the spell index?
For example:
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);
should this be applied when doing a search or when a document is indexed?
Should I clear the spellIndex when the main index changes?
I also noticed that when running some tests I found that the spell index
contained numbers from the text extracted from a document. Is there a way
to only include a*lphabetic characters in the indexDictionary process?*
Any help would be appreciated.
Cheers
