With your examples:Document 1: little boy is runningDocument 2:boy is littlea phrase query for "little boy" will match the first and not thesecond. Is that what you want?a phrase query for "litter boy" won't match either, but a generalquery might match on boy depending on how you set your must/shouldqualifiers.So maybe you should have a 2 phase approach: do a phrase query andstop if you get hits or do a general non-phrase query if you don't.Alternatively issue both at the same time but with the phrase queryboosted.--Ian.On Mon, Mar 22, 2010 at 2:13 PM, luocanrao <luocan19826...@sohu.com> wrote:> I don't think the current phrasequery can meet my requirement.>> Can someone help me implement such a phrasequery?>>>> Exact match document add some score>> All other match document add 0 score.(no matter how big slop is)>>>> For example:>> Document 1: little boy is running>> Document 2:boy is little>>>> I query "little boy">> Document 1 add score 100(Exact match)>> Document 2 add score 0( not Exact match)>> But the two document can match the query.>> user that search "litter boy" should see both the Document,>> but the Document 1 is on the top!!>>>>---------------------------------------------------------------------To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.orgfor additional commands, e-mail: java-user-h...@lucene.apache.org
