As is known, Lucene sorts all the search results according to different scores, the scores indicate the similarity between the content and keywords and it is calculated by Lucene.
But the search results are confusing sometimes. For example.
We have two wiki pages:
First Wiki: Title(design center) Content(document xxx)
Second Wiki: Title(design document) Content(abc xxx)
When we search for the keyword "Design Document", we will get design center in the first place. Some similar circumstances can also be found, articles that seem to match more will be scored smaller by Lucene. The improvement should be making the results order look more reasonable.
