I've run across some puzzling behavior regarding scoring. I have a set of documents which contain, among others, a date field (whose contents is a string in the YYYYMMDD format). When I query on the date 20030917 (that is, today), I get 157 hits, all of which have a score of .23000652. If I use 20030916 (yesterday), I get 197 hits, each of which has a score of .22295427.
So far, all seems logical. However, when I search for all records for the date 20030915, the first two (of 174 hits) have a score of 1.0, while all the rest of the hits have a score of .03125. Here is a tabulation of these and a few more queries:
Query Date Result ======= ======================== 20030917 all have a score of .23000652 (157) 20030916 all have a score of .22295427 (197) 20030915 first 2 have a 1.0 score, all rest are .03125 (174) 20030914 all have a score of .21384604 (264) 20030913 first 2 have a 1.0 score, all rest are .03125 (156) 20030912 all have a score .2166833 (241) 20030911 first 3 have a 1.0 score, all rest are .03125 (244) 20030910 all have a score of .2208193 (211)
I would expect that all the hits would have the same score, and I would expect it to be normalized to 1 (unless, I guess, the top score was less than 1, in which case normalization presumably doesn't > occur).
Does anyone have any ideas as to what might be going on here? (I'm using the latest CVS sources, obtained this afternoon.)

Terry
