Filter facet_fields with Solr similar to stopwords

[Daniel Brügge <da...@googlemail.com>]

Hi,

I am using a solr.StopFilterFactory in a query filter for a text_general
field (here: content). It works fine, when I query the field for the
stopword, then I am getting no results.

But I am also doing a facet.field=content call to get the words which are
used in the text. What I am trying to achieve is, to also filter the
stopwords from the facet_fields, but it's not working. It would only work
if the stopwords are also used during the indexing of the text_general
field, right?

The problem here is, that it's too much data to re-index every time I add a
new stopword.

My current solution is to 'filter' with code after retrieving the
facet_fields from Solr. But is there a Solr-based way to do this niftier?

Thanks & regards

Daniel

Not really. field.facet works based on the terms in the index -- if the 
term is in the index, and it's in the documents matching your query, you 
are going to get counts back for it.

OK, I've found this posting from 2009:

http://lucene.472066.n3.nabble.com/excluding-certain-terms-from-facet-counts-when-faceting-based-on-indexed-terms-of-a-field-td501104.html

But this

facet.field={!terms=WORDTOEXCLUDE}content

approach also only shows me the counting of the word I want to exclude.
