    Examine Lucene Boost() but ignore IDF (inverse document frequency)

    I'd like to boost by a doctype parameter, so that results are artificially ordered (boosted) by that type. However, as lucene also scores by the document frequency, the type that I want to boost the the least ends up at the top of my results as there are less instances of that type.

    { Category: content, LuceneQuery: (hideFromSearch:0 +(__NodeTypeAlias:dtcontenttile) +(tileContentOrigination:external^31.0 tileContentOrigination:partner^32.0 tileContentOrigination:originator^33.0)) }

    so because external has only 1 doc compared to 50 originator, external ends up the top result.

    Or maybe this just isn't something that lucene can do with it's tf/idf approach?
