Hi All,
I'm a novice in Solr and I'm continuously bumping into problems with my
custom filter I'm trying to use for analyzing a fieldType during indexing
as below;
<fieldType name="stanbolRequestType" class="solr.TextField">
<analyzer type="index">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class= "com.solr.test.analyzer.ContentFilterFactory"/>
</analyzer>
</fieldType>
Below is my custom FilterFactory class;
*public class ContentFilterFactory extends TokenFilterFactory {*
* public ContentFilterFactory() {*
* super();*
* }*
* @Override*
* public TokenStream create(TokenStream input) {*
* return new ContentFilter(input);*
* }*
*}*
I'm getting below error stack trace [1] caused by a NoSuchMethodException
when starting the server.
Solr complains that it cannot init the Plugin (my custom filter) as the
FilterFactory class doesn't have a init method; But in the example [2] I
was following didn't have any notion of a init method in the FilterFactory
class, nor I was required to override an init method when extending
TokenFilterFactory class.
Can someone please help me resolve this error and get my custom filter
working?
Thanks,
Dileepa
