Hey Bjorn, The search "aut*" is equivalent to "auto OR autotur". Lucene has no concept of which is a "better" match (both auto and autotur have "aut" followed by something, so they are both perfect matches).
The spellcheck contrib can do something vaguely like what you want, but my guess is you'd have to write your own query to accomplish what you want. (This isn't a problem that Lucene focuses on solving really.) You can just modify the wildcard query but add a boost proportional to the length of the term. Hope this helps, -Ben ----- Original Message ----- From: Björn Kremer <[email protected]> To: [email protected] Cc: Sent: Wednesday, August 17, 2011 10:07 AM Subject: Re: [Lucene.Net] Lucene search results sort order Hello, ok I see this wasn't a good sample. Here is another: I'd like to index german text. So the field "content" can e.g. contain the words "Auto" and "Autotür". If I search for "Aut*" the order is still: 1.) Autotür 2.) Auto The field "content" can contain a complete text. What analyzer should I use?
