Hi Koji,

Thanks for your reply... It is working now by setting doc and term frequency.

Regards,
Madhu.

Hi Madhu,

Check query1 and compare what you expected:

Query query1 = mlt.like(1); // mlt.like(docnumber)
System.out.println(query1.toString());

And if it is not what you expected, check min/max docFreq/termFreq/termLength
setter/getter methods described in MLT javadoc.
