Michael,
this sounds like a pretty good usecase for CustomScoreQuery
(http://lucene.apache.org/java/2_9_0/api/core/org/apache/lucene/search/function/CustomScoreQuery.html)
The org.apache.lucene.search.function package provides flexible
programmatic control over document scores. You boost up documen
Just as you can add a query that will boost better things with a
higher quality, you can add a query for a higher revenue.
Basically, the default operator "should" in boolean-clauses can be
used exactly for that: do not force this query to be matched but raise
boost if there's something tha
My initial description may have been a little abstract. Maybe I should
explain exactly what I'm trying to do. My company has various revenue
channels, one of which is per click. If a user does a search, we would
like to show results with the greatest revenue, although we don't want
people to be abl
I'm curious, can you elaborate more on the deeper use case for this?
Perhaps just implementing faceting on doc type would be sufficient?
That way users can drill in on doc type. Alternatively, I suppose you
could implement a hit collector that accesses a field cache on the doc
type field
Hi Mike,
The first thing that comes to mind is to run a query for each document
type (assuming that you have a field that stores the type) and qualify
the document type: for example type:pdf. Then you would have to write
something to combine the query results drawing an equal number of hits
Hi Mike,
I'd simply store a field "doctype" with values "pdf", "txt", "html"
and perform a separate search for each type. Although, I'd be
interested if anyone has a cooler way of doing this.
Cheers,
Phil

I was wondering if there is any way to control what kind of documents
are returned from a search. For example, lets say we have an index
built from different types of documents (pdf, txt, html, etc.). Is
there a way to have the first x results have a specified distribution
of document types? It wou
