Hi,
I would like to influence the score using geographical distance. More distant
documents lower the score.
I have sort field:
SortField geoSort = LatLonDocValuesField.newDistanceSort("location",
pos.getLatitude(), pos.getLongitude());
Then I tried add this sort field to SimpleBind

"conditionWeights" which are also available in my CQScorer class.
Now, I "just" want to get the scores from the respective query for some
document. Thus, in CQScorer's score() method, I tried "conditionScores[i] =

By wrapping the constant score query inside a BoostQuery?
That’s how elasticsearch handles boosts on arbitrary queries, for example.

Can you clarify what is the second way?
At the moment I haven't found a way (apart from creating my own Query
classes) to say that a query will always return a score of 0.5 for each
document.

Hi Stamatis,
I personally like the current way things work. If we added the ability
to set a custom score on ConstantScoreQuery, then we'd end up with two
ways to do the same thing, which I like to avoid whenever possible.

Hi all,
Currently ConstantScoreQuery [1] returns a constant score equal to 1 for
every document that matches the query.
I would like to use the ConstantScoreQuery but with a different score value
that I can pass explicitly (via the constructor for instance).
This change may also benefit some
In short: As it matches nothing, it cannot modify the score. Scores of
documents not excluded are not modified, so it behaves like zero.
In short: it's the opposite of FILTER clauses.

need the documents meets the query. I tried some way to ignore the score, like
