For example, this way: 1. Implement a filter factory:
[code] package com.mycomp.solr.analysis; import org.apache.lucene.analysis.TokenStream; import org.apache.solr.analysis.BaseTokenFilterFactory; import org.apache.solr.common.ResourceLoader; import org.apache.solr.util.plugin.ResourceLoaderAware; public class MyNewFilterFactory extends BaseTokenFilterFactory implements ResourceLoaderAware { public void inform(ResourceLoader loader) { //no need } public MyNewIndexingFilter create(TokenStream input) { return new MyNewIndexingFilter(input); } } [/code] 2. Implement the filter itself: [code] package com.mycomp.solr.analysis; import org.apache.lucene.analysis.TokenFilter; import org.apache.lucene.analysis.TokenStream; import java.io.IOException; ... /** * Allows filtering tokens in my own super-cool way */ public class MyNewIndexingFilter extends TokenFilter { public MyNewIndexingFilter(TokenStream input) { super(input); this.termAtt = addAttribute(CharTermAttribute.class); this.posAtt = addAttribute(PositionIncrementAttribute.class); } @Override public boolean incrementToken() throws IOException { // handle the token filtering if( save != null ) { // clearAttributes(); // not currently necessary restoreState(save); save = null; return true; } if (input.incrementToken()) { // do your magic return true; } return false; } } [/code] 3. compile a jar with both classes and place it into the lib directory visible to solr. Modify your schema, start solr and check the analysis page in solr admin Dmitry On Fri, Feb 24, 2012 at 12:07 PM, dsy99 <ds...@rediffmail.com> wrote: > Dear all, > I want to include my own filter for analysis of tokens while indexing the > documents in SOLR. > > Is there any explicit interface for programming compatible filters in SOLR? > > Please let me know the steps to be followed to use my own filters in > Schema.xml file.
