How to do partial word searches in Lucene.NET?

Question

I have a relatively small index containing around 4,000 locations. Among other things, I'm using it to populate an autocomplete field on a search form. My index contains documents with a Location field containing values like - Ohio - Dayton, Ohio - Dublin, Ohio - Columbus, Ohio I want to be able to type in "ohi" and have all of these results appear and right now nothing shows up until I type the full word "ohio". I'm using Lucene.NET v2.3.2.1 and the relevant portion of my code is as follows for setting up my query.... ``` BooleanQuery keywords = new BooleanQuery(); QueryParser parser = new QueryParser("location", new StandardAnalyzer()); parser.SetAllowLeadingWildcard(true); keywords.Add(parser.Parse("\"*" + location + "*\""), BooleanClause.Occur.SHOULD); luceneQuery.Add(keywords, BooleanClause.Occur.MUST); ``` In short, I'd like to get this working like a LIKE clause similar to ``` SELECT * from Location where Name LIKE '%ohi%' ``` Can I do this with Lucene?

Accepted Answer

Try this query:

```
parser.Parse(query.Keywords.ToLower() + "*")
```
