What's the .toString on the query it parsed to? Keep in mind that
"*" isn't the proper regular expression to match everything - it
would be ".*" or some other pattern.

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

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
