Hi,
I'm not sure if this is a good way to do it or not (so comments are
more than welcome!), but the way we have achieved this is using the
idea that a category/subcategory/subsubcategory etc create a path
that we associate with a document. This is the simple field
definition we use:
<fieldType name="category_facet" class="solr.TextField"
sortMissingLast="true" omitNorms="false">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.TrimFilterFactory" />
</analyzer>
</fieldType>
Then to search for all docs in say Electronics/Computers/Apple
We search submit a filter query something like:
fq=category_facet:Electronics/Computers/Apple
To get all computers we use:
fq=category_facet:Electronics/Computers*
Seems to work. I'd love to know what other people do?

such that if you search for category, you get all those documents
that have been tagged with the category AND any sub categories. If
this is possible I think I'll investigate using solr in place of
some existing code we have that deals with indexing and searching
of such data.
