Tagging in solr

[Spas Poptchev]

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
