We have indexed file name and contents in lucene index also provided search which working fine .
Now we are planning to provide auto suggestion ( similar to google search ) Used Lucene version : 4.0 we have tested with spell pkg ( org.apache.lucene.search.spell ) but in latest/next lucene version contains AnalyzingSuggester ( org.apache.lucene.search.suggest.analyzing ) Which one is best Spell OR AnalyzingSuggester . FYI : Need to migrate lucene version then only we can test AnalyzingSuggester . But now we have tested with spell pkg used in Ngram . Result is coming but we are not satisfied - we are expecting to google search . Please let us know . Thanks, Siva
