I can't seems to get it working i.e both the cases i get the
same results.
I am using the delicous sample data and trying to do
&facet.query=-field_name:[* TO *] and
&facet.query=field_name:[* TO *]
Example on delicous data
Saved Search
&facet.query=author_text:[* TO *] (12)
&facet.query=-author_text:[* TO *] (12)
&facet.query=genre_facet:[* TO *] (12)
&facet.query=-genre_facet:[* TO *] (12)
Is the above is correct behavior.. i mean
"-author_text" or "-genre_facet"
means - Don't show me any record which HAS a genre_facet?
no? shouldn't
the result be 0.. no?

You'll see what I

Yes. This works.. does that mean above is a bug..no?

However I am not sure I did the test correctly. But lets
take the
delicous data for this explanation. If you try the search
box -- right side
and type in -- you will see a drop down list with david(2).
Now
what I would like to show to the user is the following
Internet (4) .. which is not a problem as we are already
doing that in flare.
But in a case where i don't know the what is in my index I
would like to show
"top query terms" or "top 100 query
terms" or "all queries having more then 50
matches" etc. But present it in following way... for
the above example
Internet (4)
- genere_facet (2)
- description_text (2)
Well, I am after newsmap. I need to develop that
functionality.. in newsmap
you have facets which are geographic (Uk, US, World) and
subject matter
(Technology, Business, etc).. in my case there are lot more
subject matter but if
you look at newsmap you will see that they have "a news
title" and when you move
the mouse you will see "number of times the news item
is in the media". I am
not sure I can do that with solr out of the box.. well I
started to look
at the search end of the puzzle for my project today.. I
will soon find out.
Again I appreciate your help and time. Any pointers are
always welcome
Regards
