扩展ik原生代码：

public class IKAnalyzerTokenizerFactory extends TokenizerFactory

{

private boolean useSmart;

public boolean useSmart()

{

return this.useSmart;

}

public void setUseSmart(boolean useSmart) {

this.useSmart = useSmart;

}

public IKAnalyzerTokenizerFactory(Map<String, String> args) {

super(args);

assureMatchVersion();

setUseSmart(((String)args.get("useSmart")).toString().equals("true"));

}

public Tokenizer create(AttributeSource.AttributeFactory factory, Reader input)

{

Tokenizer _IKTokenizer = new IKTokenizer(input, this.useSmart);

return _IKTokenizer;

}

}

将ik重新打包，solr中配置信息如下：
