You have to provide some more details to get meaningful help. You say "I was trying to use boosting". How? At index time? Search time? Both? Can you provide some code snippets? What does your schema look like for the relevant field(s)?
You say "but seems not working right". What does that mean? No hits? Hits not ordered as you expect? Have you tried putting "&debugQuery=on" on your URL and examined the return values? Have you looked at your index with the admin page and/or Luke to see if the data in the index is as you expect? As far as I know, boosts are multiplicative. So boosting by a value less than 1 will actually decrease the ranking. But see the Lucene scoring, See: http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/search/Similarity.html And remember, that boosting will *tend* to move a hit up or down in the ranking, not position it absolutely.
