Harry , basically converting score into range 0 to 100 require normalization(dividing each score with highest record and multiply by .100) .but this score does n't represent matching %.

Hi Rajendra, Thanks for your reply. Normalization is good way to solve it. But there is problem, if normalize by your formula, the score of top one doc would be 100. Although it map score range from 0~100, but the score maybe not show the similarity between query and hit docs. My system is to search POI. And I want final score to show they text similarity. It like inverse of levenshtein distance of query and hit docs. Do you have any ideas.
