Is it possible to specify a pattern of Ranking while querying the indexes?

I want to specify a particular pattern in which results are retrieved for a
query. Can a pattern of ranks be specified in the query ?

Have you seen boosting query (bq parameter) in DisMax? Does that not satisfy
your constraints?

Re: Is it possible to specify a pattern of Ranking while querying the indexes?

Posted by tushar kapoor <tu...@rediffmail.com>.

In case I dont want to write a plugin code for that, what is the option that
I am left with ?

As I see it, one of the solution is to add a new a ranking field and query
on the basis of ascending/descending values of the ranking filed.
To change the sort order change the value of the ranking field by
re-creating indexes. 

Is there any other way of doing it ?

Well that is not very well defined. I suppose if you can mathematically
defined an ordering, you can implement it by writing some plugin code.

Re: Is it possible to specify a pattern of Ranking while querying the indexes?

Posted by tushar kapoor <tu...@rediffmail.com>.

What I need is a specific sorting order in which the documents are retrieved.
The only way I know that this is possible is using something like this -

widescreen AND HDTV^2; popular desc, score desc;

as given on 
http://wiki.apache.org/solr/SolrRelevancyCookbook?highlight=%28ranking%29
http://wiki.apache.org/solr/SolrRelevancyCookbook?highlight=%28ranking%29 

Can I specify an order other than ascending or descending.


For instance, if I have a 'Product' field in indexes with values
P1,P2,P3,P4....

If I query like this - (queryString);Product desc;

Result would be - ....,P4,P3,P2,P1

Now I want the order to be ....,P3,P2,P1,P4. Is this possible ?

Can you give an example of what you mean?
