Tagging in solr

Hi,
 
what i want to do is to store tags that belong to products.
Each tag should also store information about how often it
was used with a certain product.
So for example:
 
product1
cool 5        => product1 was tagged 5 times with cool
 
What would be the best way to implement this kind of stuff
in solr?
 
Btw. its a huge database with over 500000 products.
 
cheers,
Spas

There is a wiki page on some brainstorming on how to
implement  
tagging within Solr: <http://
wiki.apache.org/solr/UserTagDesign>

It's easy enough to have a tag_keywords field, but updating
a single  
tag_keywords field is not so straightforward without sending
the  
entire document to Solr every time it is tagged.  See
SOLR-139's  
extensive comments and patches to see what you're getting
into.

thanks for your help thorsten.

I have a general idea how the schema file (for the
UserTagDesign) should look like but its the first time im
working with solr, so im not so familiar with the subtleties
of solr. If you could give me an example how the schema
should be implemented (especially the analyzers for the utag
and utag2) i would really appreciate it.

Is it possible to have these kind of tags in a catch-all
field and is there any chance not to involve the user (just
saving how many times this tag was used on a product)?

cheers,
Spas

Hi,

   This is what I intended to do with my impl. Create a
Multi-Valued filed
for the schema. Then when you prepare the document which you
want to send it
to the SOLR to index, for examples
<doc>
 <productID>1234</productID>
 ....
 ...
 ...
 <tag>Java</tag>
 </tag>.Net</tag>
</doc>

 And the next question of your to get the count do the facet
on this <Tag>
field.
