This is the phonetic filter at work (the double metaphone filter, if I'm guessing correct); to be able to do phonetic searches the search string is run through the phonetic filter, which returns a search string converted to the phonetic form. PRODUCT gets converted to PRTK as those are the four letters that are considered important, and C and K are considered to be the same (produkt vs product) (in this case). You can read more about metaphone and double metaphone at wikipedia. The phonetic filter should be run against a field by itself, and not on the complete query string (or the regular query fields). That would also allow you to weight the phonetic hit less than an exact hit. You could also consider changing the algorithm used or write your own phonetic factory. I wrote a small blog post when I did this a year ago. http://e-mats.org/2008/06/writing-a-solr-analysis-filter-plugin/ Hope that helps. --mats
