SpanRegexQuery causes error

[Luke Tan]

Hi,

I am using code in
http://mail-archives.apache.org/mod_mbox/lucene-java-user/200605.mbox/[EMAIL 
PROTECTED]

for wildcard search in phrase

but it seems that I can only search something like:

"one two three word*"

but not

"one * three word"

It throws error:


java.lang.NullPointerException
   at java.util.Hashtable.get(Hashtable.java:336)
   at org.apache.lucene.index.MultiReader.norms(MultiReader.java:163)
   at org.apache.lucene.search.spans.SpanWeight.scorer(SpanWeight.java:70)

   at org.apache.lucene.search.Hits.<init>(Hits.java:52)
   at org.apache.lucene.search.Searcher.search(Searcher.java:53)

The query text is analyzed using this:

       if (!StringUtils.isEmpty(queryText)) {
           if (queryText.indexOf("*") == 0 || queryText.indexOf("?") == 0)
return null;

           if (queryText.indexOf(' ') != -1) {
               SpanRegexQuery srq = new SpanRegexQuery(new Term(field,
queryText));
               SpanFirstQuery sfq = new SpanFirstQuery(srq, 1);
               return sfq;
           }
       }
Query getFieldQuery(String field, String queryText) throws ParseException

Thanks
Luke
