Your question is better suited for the solr-u...@lucene mailing list ... not the solr-...@lucene list. solr-dev is for discussing development of the internals of the Solr application ... it is *not* the appropriate place to ask questions about how to use Solr (or write Solr plugins) when developing your own applications. Please resend your message to the solr-user mailing list, where you are likely to get more/better responses since that list also has a larger number of subscribers. : Date: Fri, 6 Nov 2009 13:03:03 +0800 : From: Tang Minzhi <minzhit...@ethos.com.cn> : Reply-To: solr-dev@lucene.apache.org : To: "solr-dev@lucene.apache.org" <solr-dev@lucene.apache.org> : Subject: union functionality? : : Hey everyone, : : I'm newbie to solr. : : I have a question below: : Assume that I have the fields 'item_name' and 'category_name', like : item_name | category_name : apple fruit : orange fruit : rice grain : corn grain : strawberry fruit : beef meat : .... : : I want to fetch the result set of "top 2 item of each categories I specified (might be 2 of them 'fruit', 'grain')" at one time, instead of fetch them through several requests, is it possible with solr? : : It seems that in mysql database, there's union functionality which can combine several request queries together, so how about solr? : : Thanks. : : Best regards, : -------------------------------- : Minzhi Tang : Skype: minzhitang : MSN: tmin...@hotmail.com -Hoss
