Re: multi level faceting
Hi, there are two relative similar solutions for this problem. I will describe one of them: * create a multivalued string field called 'category' * you have a category tree. so make sure a document gets not only the leaf category, but all categories (name or id) until the root * now facet over category with '-1' as limit * What if you want to display only the categories of one level? (e.g. if you don't want other level at a time or if they are too much). then use index the category field ala level_category and use facet.prefix to filter the category list * clicking on a category entry should result in a filter query ala fq=category:selectedCategoryWithLevel the little tricky part is now that your UI or middle tier has to parse the level e.g. 2 and the append 2+1=3 to the query: facet.prefix=3_ * if you filter the level then one question remains: Q: how can you display the path from the selected category until the root category? A: Either get the category parents via DB (which is easy if you store the category ids in solr) or get the parents from the parameter list which is a bit more complicated (in this case I think it is best to store the category names in solr). (The second approach is: instead of using facet.prefix you can use dynamic fields ala category_level_s) Did this explaination is missing sth. or unclear? Kind Regards, Peter. Hi, there is a solution without the patch. Here it should be explained: http://www.lucidimagination.com/blog/2010/08/11/stumped-with-solr-chris-hostetter-of-lucene-pmc-at-lucene-revolution/ If not, I will do on 9.10.2010 ;-) Regards, Peter. I've a similar problem with a project I'm working on now. I am holding out for either SOLR-64 or SOLR-792 being a bit more mature before I need the functionality but if not I was thinking I could do multi-level faceting by indexing the data as a String like this: id: 1 SHOE: Sneakers|Men|Size 7 id: 2 SHOE: Sneakers|Men|Size 8 id: 3 SHOE: Sneakers|Women|Size 6 etc and then in the UI, show just up to the first delimiter (you'll have to sum the counts in the UI too). Once the user clicks on Sneakers, you would then add fq=SHOE:Sneakers|* to the query and then show the values up to the 2nd delimiter, etc. Alternatively, if you didn't want to use a wildcard query, you could index each level separately like this: id: 1 SHOE1: Sneakers SHOE2: Sneakers|Men SHOE3: Sneakers|Men|Size 7 Then after the user clicks on the 1st level, fq on SHOE1 and show SHOE2, etc. This wouldn't work so well if you had more than a few levels in your hierarchy. I haven't actually tried this and like I said I'm hoping I could just use a patch (really I hope 3.x gets released GA with the functionality but I won't hold my breath...) But I do think this would work in a pinch if need be.

I've a similar problem with a project I'm working on now. I am holding out
for either SOLR-64 or SOLR-792 being a bit more mature before I need the
functionality but if not I was thinking I could do multi-level faceting by
indexing the data as a String like this:
id: 1
SHOE: Sneakers|Men|Size 7
id: 2
SHOE: Sneakers|Men|Size 8
id: 3
SHOE: Sneakers|Women|Size 6
etc
and then in the UI, show just up to the first delimiter (you'll have to sum
the counts in the UI too). Once the user clicks on Sneakers, you would
then add fq=SHOE:Sneakers|* to the query and then show the values up to the
2nd delimiter, etc.
Alternatively, if you didn't want to use a wildcard query, you could index
each level separately like this:
id: 1
SHOE1: Sneakers
SHOE2: Sneakers|Men
SHOE3: Sneakers|Men|Size 7
Then after the user clicks on the 1st level, fq on SHOE1 and show SHOE2, etc.
This wouldn't work so well if you had more than a few levels in your
hierarchy.
I haven't actually tried this and like I said I'm hoping I could just use a

Subject: Re: multi level faceting
I think that is just sending 2 fq facet queries through. In Solr PHP I
would do that with, e.g.
$params['facet'] = true;
$params['facet.fields'] = array('Size');
$params['fq'] = array('sex' = array('Men', 'Women'));
but yes i think you'd have to send through what the current facet query
is and add it to your next drill-down

Hi,
I was wondering if there's a way to display facet options based on
previous facet values. For example, I've seen many shopping sites
where
a user can facet by Mens or Womens apparel, then be shown sizes
to
facet by (for Men or Women only - whichever they chose).
Is this something that would have to be handled at the application
level?
