Hi Ronny,
Have you looked at your explanation page to see where the document score is
coming from? Often this is very helpful, especially when the rankings are not
what you would expect.
Luke doesn't show you the boosts you set, from my experience. Don't be
concerned if Luke always says 1.
You say that the actual parking document has parking as part of a combined
word. What analyzer are you using? Are you stemming? If you're only matching
exactly, parkingxxxx won't match parking. That's just something to keep in
mind.
First step I'd suggest: check your explanation page. That will tell you how
many times it's matching each field in each document.
Good luck, and have a good day,
Ann

Subject: The ranking is wrong
I have indexed our intranet with Nutch-0.9.
I do a query 'parking location:stavanger language:no' and I recive some
hits. (two extra fields added)
The Nutch client ranks the hits not quite as expected.
1. Transport and parking - Stavanger Airport, Sola
2. Frontpage - Stavanger Airport, Sola
3. Parking - Stavanger Airport, Sola
How it should have been
1. Parking - Stavanger Airport, Sola
2. Transport and parking - Stavanger Airport, Sola
3. Frontpage - Stavanger Airport, Sola (should not have been there at
all if possible, but I recon it is not easy to not index a navigation
menus since they are part of the page)
The page "Parking - Stavanger Airport, Sola" has parking in the title,
parking in the content (20+ times in some way, mostly combined words
like xxxparking, or parkingxxx, but also about 5 times as only parking)
and even parking in the url.
I guess I have to alter the boosting for some fields. I tried to up the
boost in index-basic plugin (hardcode it), but I can't see any changes
in the index. Luke tells me that the field index still is 1.0 even after
I changed them. Am I doing it wrong?
Even if I search only for 'parking' and not filtering on location I
recive a lot of hits but all is frontpage for the different frontpage.
All of this pages seem to have a high boost outranking the real parking
page (s) big time.
Any help is appreciated.
Best regards,
Ronny N.
