Indexing and searching French text with diacritics in Lucene

Answer 1

Do you use a ISOLatin1AccentFilterFactory in the analyzers for the field where this text is indexed? Make sure that if you have it for the index analyzer, you also have it for the query analyzer.

Answer 2

BTW. If you are using ISOLatin1AccentFilter note that it was deprecated in favor of ASCIIFoldingFilter

Answer 3

I am not using ISOLatin1AccentFilter. I am using FrenchAnalyzer provided with LUCENE.

When I see index using luke The index file does not contain multimédia/ français/ étrangère words.

Please help..

Basically, you have 2 options:

1. Index and search your French files with Snowball analyzer for French
2. Index your French docs as usual, but search with FuzzyQuery (not very accurate, but may be enough in your particular case).
