copied!<p>I do not believe Lucene supports anything like this, nor do I believe it has a trivial solution. </p> <p>"Fuzzy" searches do not operate on a fixed number of characters. <code>bla~</code> may for example match <code>blah</code> and so it must consider the entire term.</p> <p>What you could do is implement a query expansion algorithm that took the query <code>bla~*</code> and converted it into a series of OR queries</p> <pre><code>bla* OR blb* OR blc OR .... etc. </code></pre> <p>But that is really only viable if the string is very short or if you can narrow the expansion based on some rules.</p> <p>Alternatively if the length of the prefix is fixed you could add a field with the substrings and perform the fuzzy search on that. That would give you what you want, but will only work if your use case is sufficiently narrow.</p> <p>You don't specify exactly why you need this, perhaps doing so will elicit other solutions.</p> <p>One scenario I can think of is dealing with different form of words. E.g. finding <code>car</code> and <code>cars</code>.</p> <p>This is easy in English as there are word stemmers available. In other languages it can be quite difficult to implement word stemmers, if not impossible.</p> <p>In this scenario you can however (assuming you have access to a good dictionary) look up the search term and expand the search programmatically to search for all forms of the word.</p> <p>E.g. a search for <code>cars</code> is translated into <code>car OR cars</code>. This has been applied successfully for my language in at least one search engine, but is obviously non-trivial to implement.</p>
