Leading wildcard character throws error in Lucene.NET

Question

If the search query contains a leading wildcard character (* or ?), the QueryParser\'s Parse function throws an error.

Answer 1

You can avoid wildcard queries by utilizing NGramFilter for your index analyzer. Than you have to use search_analyzer without NGramFilter. This way you can search similar to like "%text%" without even needing wildcards. You just enter 'abc' and your index would be searched for all entries containing 'abc' very quickly.
