Using stored terms for faceting

[Peter Karich <pe...@yahoo.de>]

Hi,

is it possible to use the stored terms of a field for a faceted search?

I mean, I don't want to get the term frequency per document as it is
shown here:
http://wiki.apache.org/solr/TermVectorComponentExampleOptions

I want to get the frequency of the term of my special search and show
only the 10 most frequent terms and all the nice things that I can do
for faceting.

At the moment I am calculating the terms for every document and index
them into a separate multivalued field where I can then easily apply
faceting.
But is there a better way?

Regards,
Peter.

This is simple faceting, doesn't even have to be a multi-valued  
field.  Just index your description field with the desired stop word  
removal and other analysis that you want done, and  
&facet.field=description

Re: Using stored terms for faceting

Dear Hoss,

I will try to clarify what I want to achieve :-)

Assume I have the following three docs:

id:1
description: bmx bike 123

id:2
description: bmx bike 321

id:3
description: a mountain bike

If I query against *:* I want to get the facets and its document count ala:
bike: 3
bmx: 2

I reached this with the following approach:
I skip the noise words like 'a'. E.g. for doc 3 I will get the terms
'mountain' and 'bike'.
Those two terms will then additionally indexed to a multivalued e.g.
myfacet so that I can do faceting on that field.

Is there a simpler approach?

Regards,
Peter.

No, the only thing stored fields can be used for is document centric 
opterations (ie: once you have a small set of individual docIds, you can 
access the stored fields to return to the user, or highlight, etc...)

i honestly have no idea what you are saying you want -- can you provide 
a concrete use case explaining what you mean?  describe some example data 
and then explain what type of logic owuld happen and what type of result 
you'd get back?
