Hi,

Custom similarity returning 1 in coord factor?

http://lucene.apache.org/core/4_6_0/core/org/apache/lucene/search/similarities/TFIDFSimilarity.html#coord(int,%20int)

We have a search that takes text from two different fields and then searches against \
3 different fields.

The two input fields are a summary and description, and the fields we're searching in \
are issue, title, and body. We'd like to essentially perform the 2 queries and then \
add up their score. We'd also like to boost the summary query and the issue field. \
Here's what I have right now (slightly simplified):

_query_:"{!edismax qf='issue^2 body title' boost=1.5}<summary query>" OR \
_query_:"{!edismax qf='issue^2 body title'}<description query>"

The problem with this is that if either summary or description don't match to \
anything in a result, the result gets penalized with coord(1/2). I would like to \
simply add the two together and ignore the coord. Is there a way to do this?
