Thanks for the plug Erick, but my deep dive doesn't go quite that deep
(yet.)
But I'm sure a 2,500 page book on how to develop all manner of custom Solr
plugin would indeed be valuable though.
But I do have plenty of example of using the many builtin Solr analysis
filters.

Well, I think Jack Krupansky's book has some examples, at $10 it's probably
a steal.
Best,

Hi Erick,
Thanks a lot for the pointer.
I looked at the LowerCaseFilterFactory class [1] and it's parent abstract
class AbstractAnalysisFactory API [2] , and modified my custom filter
factory class as below;
public class ContentFilterFactory extends TokenFilterFactory {
public ContentFilterFactory() {
super();
}
@Override
public void init(Map<String, String> args) {
super.init(args);
}
@Override
public ContentFilter create(TokenStream input) {
assureMatchVersion();
return new ContentFilter(input);
}
}
I have called the parent's init method as above, but I'm still getting the
same error of : java.lang.NoSuchMethodException: com.solr.test.analyzer.
ContentFilterFactory.<init>(java.util.Map)
Any input on this?
Can some one please point me to a doc/blog or any sample to implement a
custom filter with Solr > 4.0
I'm using Solr 4.5.0 server.
Thanks,
Dileepa
