Note that you now have a much better alternative to FieldCache with doc
values, which are computed at index-time, stored in the index and won't
blow up memory.

I don't think the big-O notation is appropriate to measure the cost of
Lucene queries.

What if we have some assumptions. For example, we assume that we have only
one segment and the entire segment is in memory ?

Sigh. Yeah, I agree that a simple big-O won't work for Lucene. But
nonetheless, we really should have some sort of performance
characterization. When people ask me about how to characterize Lucene/Solr
performance I always tell them that it is highly non-linear, with lots of
optimizations and optio
