 `position_linear`:::
 `weightFieldValue * (1 - 0.10*position)`: Matches to the start will be given a higher score. This is the default.
 `position_reciprocal`:::
-`weightFieldValue / (1 + position)`: Matches to the start will be given a score which decay faster than linear.
+`weightFieldValue / (1 + position)`: Matches to the start will be given a higher score. The score of matches positioned far from the start of the suggestion decays faster than linear.
 `position_exponential_reciprocal`:::
-`weightFieldValue / pow(1 + position,exponent)`: Matches to the start will be given a score which decay faster than reciprocal.
+`weightFieldValue / pow(1 + position,exponent)`: Matches to the start will be given a higher score. The score of matches positioned far from the start of the suggestion decays faster than reciprocal.
 `exponent`::::
-An optional configuration variable for `position_reciprocal` to control how fast the score will decrease. Default `2.0`.

 `numFactor`::
 The factor to multiply the number of searched elements from which results will be pruned. Default is `10`.
