Hi John/Mark,

We have a search feature where we are using metamorph inverted index on three columns Expertise/Tags/Business_title. When I search through it for "knowledge management" I get some results I see a result which has the initial two columns blank and is ranked high as there is exact term in the Business_title field. I understand the basics of the index. But is there any way, that we can still rank the third column lower than the first two whether or not they contain text?

Currently the likepleadbias is set high to 1000, likepdocfreq=0 and other ranking knobs to their default value and likepallmatch=1.

Thanks & Regards,
Priti

Not easily, as the ranking is based on the word number in the concatenated field. One approach to push it down a little would be to add index expressions of:

>>=[\x0a\x0d]=
>>=[\x0a\x0d]\P=[\x0a\x0d]=

so that there would be one or two words (the blank lines between fields) indexed ahead of Business_title.
