It wouldn't be too hard to write a Solr Plugin that take a param docId together
with a query and return the position of that doc within the result list for
that query. You will still need to deal with the performance though. For
example, if the doc ranks at one millionth, the plugin still
Oh, I see what you are trying to do, you were confusing :)
To get the exact position of a particular document in the ranked list, you will
need to loop through the whole list, as that's exactly what Solr has to do to
get to the that document.
However, you could do some optimization with the

Lucene main file formats actually don't change a lot in 4.x (or even 5.x), and the newer codecs just delegate to previous versions for most file types. The newer file types don't typically include Lucene's version in file names.For example, Lucene 4.6 codes basically delegate stored fields and
Taminidi,Relevance ranking is tricky and very domain specific. There are usually multiple ways to do the same thing, each is better at some edge cases and worse at some others :)It looks to me that you are trying to rank the products by: exact match on SKU, then exact match onManufactureSKU, then
1. Yes, that's the right way to go, well, in theory at least :)2. Yes, queries are alway fanned to all shards and will be as slow as the slowest shard. When I looked intoSolr distributed querying implementation a few months back, the support for graceful degradation for thingslike networkfailures

I don't think there's a synonym file for this use case. I am not even sure if

I think the better way to improve recall is to mark up your documents with
a hidden field of is the geographic relations. For example, before indexing,
you can add a field to all
