Yep, what you describe is what I do in similar situations, it works fine. It is certainly possible to facet on a tokenized field... but your individual facet values will be the _tokens_, not the complete values. And they'll be the post-analyzed tokens at that. Which is rarely what you want. Thus the use of two fields, one tokenized and analyzed, one not tokenized and minimimally analzyed (for instance, not stemmed). ________________________________________ From: elisabeth benoit [elisaelisael...@gmail.com] Sent: Thursday, April 28, 2011 9:03 AM To: solr-user@lucene.apache.org Subject: Re: fq parameter with partial value
yes, the multivalued field is not broken up into tokens. so, if I understand well what you mean, I could have a field CATEGORY with multiValued="true" a field CATEGORY_TOKENIZED with multiValued=" true" and then some POI <field name="NAME">POI_Name</field> ... <field name="*CATEGORY*">Restaurant Hotel</field> <field name="CATEGORY_TOKENIZED">Restaurant</field> <field name="CATEGORY_TOKENIZED">Hotel</field> do faceting on CATEGORY and fq on CATEGORY_TOKENIZED. But then, wouldn't it be possible to do faceting on CATEGORY_TOKENIZED?
