Is there any proposal to add a proper NEAR (proximity) operator to the
default query language that can handle phrase proximity, implemented as
SpanNearQuery?
With all the conversations about density queries and searching for
"concepts" that appear in different fields, it just seems logical to

This is a very interesting thread. Down is a link to a paper I published many

What is described here as "Passage Search" is nothing more than a
PhraseQuery with a large slope. I think it's a UI problem rather than a
ranking algorithm. For example you may want to have translate simple
multi-term queries into phrasequery by default (instead of AND or OR).
Let's say search you
I'm interested in obtaining the individual scores of the top-level
sub-queries (query or Boolean clauses) when searching using a
BooleanQuery. The main purpose is to visualize scores of individual
queries representing concepts connected through a OR/AND operators
representing the union or intersect
I think Doug is right. Generic names such as OS (vs. Linux), Web Server
(vs. Apache WS) or Servlet Engine (vs. Tomcat) although technically

collection of TREC or other benchmark text
corpus induces tailoring the algorithms to the corpus. To be fair we
should run the benchmarks against multiple collections and average
recall/precision.

s also seams like a good start also for calculations of merged relevance ranking
when exact values of multiple ranking systems/algorithms cannot be obtain or are not
compatible but ranking order is available.
Sorry fr this long email Just my 2 cents.
