Hello, I'm running a test of my query and mapping shown here: > I'm searching for "pauljones" in the uname field. In the results the fifth document containing "pauljones10297" has a score of 16.027834, while the 6th document containing "PaulJones" has a score of 5.008698. Why is the score for the 5th document so much higher than the 6th? Regards, Eric -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

The difference is the fieldNorm. This field holds any boosts (both document and field level) and any length normalization. It is only 1 byte, so it is incredibly lossy. Did you apply an index time boost to either the field or document? Have you tried disabling norms on ngram fields? Which version of elasticsearch are you using? I noticed you used the old format "omit\_norms":true instead of "norms": { "enabled": false } -- Ivan On Thu, Mar 27, 2014 at 1:28 PM, Eric T [ewltang@gmail.com](mailto:ewltang@gmail.com) wrote: > Hello, > > I'm running a test of my query and mapping shown here: > [gist:9c00155525784b620ca9 · GitHub](https://gist.github.com/ewltang/9c00155525784b620ca9) > > I'm searching for "pauljones" in the uname field.

Hi Ivan, No I don't apply any boost at index time. I did not disable norms on the uname.autocomplete field, I will have to get back to you on the result. I'm using 0.90.2. thanks Eric On Thu, Mar 27, 2014 at 8:55 PM, Ivan Brusic [ivan@brusic.com](mailto:ivan@brusic.com) wrote: > The difference is the fieldNorm.

I created a new index that includes both the old "autocomplete" multi-field and a new multi-field called "autocompletenew" that contains omit\_norms : true I did the same query on the two fields and the results are here > The scoring is consistent for both but I find the query on the original field seems to return results that make more sense to me. For example "PaulJones" is the first result and then followed by PaulJones with one numerical digit. The second result is more random with "PaulJones" being second. The rest of the results contain longer variations of PaulJones. I was expecting that the query on autocompletenew to return the results that the query on the original field returns. I also didn't expect the first query to return the results that I want since the multi-field doesn't have omit\_norms: true. Is this the expected behaviour?
