Score is always NaN

I have an index with a file crawler.

My prolem is that queries return no score (score=NaN). It occurs with the API
and in the admin user interface.

However, score seems to exist : in the admin UI, score explanation file
contain score.

In the admin UI, in the result part part of a query, I have : "#0 - Score: NaN
- Collapsed: 0 - docId: 4511"

Is this a normal behavior?

Hi,

The score is not displayed when the query is sorted. To check this:

Remove all the lines in the Sort panel of the query.

Save the query

Do another test

By default, the query is sorted by descending score.

Best,

Emmanuel.

P.S.: Sorry for this late reply ...

It work when there is no sorted field.

But how to weight the score with the filesystem date, in order to have recents
files higher then older ones?
