Re: The way to customize ranking?
: I'm working on Solr to build a local business search in China. We have a : special requirement from advertiser. When user makes a search, if the : results contain paid advertisements, those ads need to be moved on the top : of results. For different ads, they have detailed rules about which comes : first. You haven't specified wether the paid ads are global (ie: move to the top of any search that they match) or search specific (ie: company A paid for their ad to be at the top of the searchess for X and Y, company B paid for their ad to be at the top of searches for Z) If you want the later, QueryElevationComponent is perfect for you. If you want the former then just add a field to your schema indicating the ad_priority. it can be how much they paid, or a ranking number -- whatever you already have about the importance of the ad. Make sure you either give every doc a default ad_priority, or use 'sortMissing=last' in your schema.xml, and then sort on your ad_priority field before sorting on score... q=foosort=ad_priority+desc,score+desc Doc: id=23, name=Ford, ad_priority=0 Doc: id=45, name=Honda Civic, ad_priority=0 ... Doc: id=99, name=Paid Ad, ad_prioriy=99 -Hoss
Re: The way to customize ranking?
You can use CustomScoreQuery to combine a scalar field value (e.g. like the amount of the paid placement) together with the textual relevancy. You can combine things anyway you want, e.g. finalScore = textualScore + 1000.0 * scalarValue. Or whatever makes sense. It sounds like you want some kind of step function, where if there is any scalar value, that overwhelms the score. This could do that for you. -- View this message in context: http://lucene.472066.n3.nabble.com/The-way-to-customize-ranking-tp4002885p4003565.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: The way to customize ranking?
Hi You might add an int field Search Rule that identifies the type of search. example Search Rule Description 0 Unpaid Search 1 Paid Search - Rule 1 2 Paid Serch - Rule 2 You can use filterqueries (http://wiki.apache.org/solr/CommonQueryParameters) like fq: Search Rule :[1 TO *] Alternatively, You can even use a boolean field to identify whether or not a search is paid and then an addtitional field that identifies the type of paid search. -- karthick On Thu, Aug 23, 2012 at 11:16 AM, Nicholas Ding nicholas...@gmail.comwrote: Hi I'm working on Solr to build a local business search in China.

Re: The way to customize ranking?
Thank you, but I don't want to filter those ads. For example, when user make a search like q=Car Result list: 1. Ford Automobile (score 10) 2. Honda Civic (score 9) ... ... ... 99. Paid Ads (score 1, Ad has own field to identify it's an Ad) What I want to find is a way to make the score of Paid Ads higher than Ford Automobile. Basically, the result structure will look like - [Paid Ads Section] [Most valuable Ads 1] [Most valuable Ads 2] [Less valuable Ads 1] [Less valuable Ads 2] - [Relevant Results Section] On Thu, Aug 23, 2012 at 11:33 AM, Karthick Duraisamy Soundararaj karthick.soundara...@gmail.com wrote: Hi You might add an int field Search Rule that identifies the type of search. example Search Rule Description 0 Unpaid Search 1 Paid Search - Rule 1 2 Paid Serch - Rule 2 You can use filterqueries ( http://wiki.apache.org/solr/CommonQueryParameters) like fq: Search Rule :[1 TO *] Alternatively, You can even use a boolean field to identify whether or not a search is paid and then an addtitional field that identifies the type of paid search. -- karthick On Thu, Aug 23, 2012 at 11:16 AM, Nicholas Ding nicholas...@gmail.com wrote: Hi I'm working on Solr to build a local business search in China.

Re: The way to customize ranking?
I cant think of a way you can achieve this in one request. Can you make two different solr requests? If so, you can make on with fq=PaidSearch:0 other with fq=padidSearch:[1:*] .

Re: The way to customize ranking?
I would create two indices, one with your content and one with your ads. This approach would allow you to precisely control how many ads you pull back and how you merge them into the results, and you would be able to control schemas, boosting, defaults fields, etc for each index independently.

Re: The way to customize ranking?
Could you not apply this logic in your solr client prior to displaying the results?

Re: The way to customize ranking?
Yes, I think do two separate calls to Solr could solve my problem. But I really want to reduce the HTTP requests to Solr, if I could write a Solr extension and place my ranking logics to inside, that could be perfect.
