Subject Re: Delete Document from Index. How?
Date Fri, 12 Nov 2010 12:07:22 GMT
Looked at 2.2 api and those methods should be there. So the
NoSuchMethodException makes no sense.
Are you absolutely sure that your integration between PHP & Java is setup
properly and you really are using 2.2?
Could there be multiple versions of lucene jars in your classpath? such that
older ones might be getting in your way and you wouldn't really be accessing
the 2.2 jars?
