Subject Re: Field Boosting
Date Fri, 18 Nov 2005 12:08:50 GMT
titleField.setBoost((float)1.8);
doc.add(titleField);

keywordField.setBoost((float)1.6);
doc.add(keywordField);

summaryField.setBoost((float)1.2);
doc.add(summaryField);

When searching.

field.getBoost() always = 1.0

Daniel,

Could you give us a test case that shows the boost not working properly?

I'm using document level boosting (which is really what field level

working as expected.
