Hi, I just spotted something weird, again. A regular search popped up a weird candidate for first result, so i've reproduced it on our production system.
Digging deeper, it appears that the fl parameter has something to do with it. Not the order of results but the scores / explain in the debug section are different. This means i am not sure in what case the debugging information is really correcty. Check this out. These are the top four results with fl=title_nl,score,id&hl=false&facet=false&debugQuery=true&wt=xml&indent=true&q=misofonie&rows=4 <result name="response" numFound="26" start="0" maxScore="153.99518"> <doc> <str name="id">http://www.gezondheidenco.nl/179901/website-over-misofonie-online/</str> <str name="title_nl">Website over misofonie online</str> <float name="score">153.99518</float></doc> <doc> <str name="id">http://www.gezondheidenco.nl/tag/misofonie/</str> <str name="title_nl">misofonie Archives - Gezondheid & Co</str> <float name="score">149.88002</float></doc> <doc> <str name="id">http://www.gezondheidenco.nl/263802/misofonie-psychische-aandoening-is-behandelen/</str> <str name="title_nl">Misofonie: een psychische aandoening.

But i vaguely remeber something about this before, but cannot find references. Any idea? Thanks, Markus
