Creates a new instance of the provider class for the given IndexReader.

Explain the custom score. Whenever overriding {@link #customScore(int, float, float)}, this method should also be overridden to provide the correct explanation for the part of the custom scoring.

Explain the custom score. Whenever overriding {@link #customScore(int, float, float[])}, this method should also be overridden to provide the correct explanation for the part of the custom scoring.

* Compute a custom score by the subQuery score and a number of ValueSourceQuery scores.

Subclasses can override this method to modify the custom score.

If your custom scoring is different than the default herein you should override at least one of the two customScore() methods. If the number of ValueSourceQueries is always < 2 it is sufficient to override the other {@link #customScore(int, float, float) customScore()} method, which is simpler.

The default computation herein is a multiplication of given scores:

                ModifiedScore = valSrcScore * valSrcScores[0] * valSrcScores[1] * ...
            

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Returns a String that represents the current Object.
