I already asked this on StackOverflow. Unfortunately without any answer for over a week now.
Therefore again to the real experts: I downloaded a list of 350.000 English words in a .txt file and Indexed it using the latest Lucene (6.2). I want to apply wildcard queries like aard???? and then retreive a list of matches. I've done this before in an older version of Lucene. Here it was pretty simple. I just had to do a Query.rewrite() and this retuned what I needed. Unfortunately in 6.2 this doesn't work anymore. There is a Query.rewrite(Indexreader reader) which should return a HashMap of Terms. In my case there's only one matching Term (aardvark). The Searcher returns one hit, containing the Document path to the wordlist. The HashMap is however empty. When I change the Query to find more then one single match (like aa*) the HashMap remains empty. I tried the MatchExtractor too. Unfortunately without result. The Objective of this is to demonstrate the power of Lucene to easily find words of a particular length, given one or more characters. I'm pretty sure I can do this using regular expressions in Java but then it's outside my objective. Can anyone tell me why this isn't working? I use the StandardAnalyzer. Should I use a different Application? Any help is greatly appreciated. Thanks. -- Sent from Gmail IPad
