I want to add "tags" to product, and these tags can be searched.
my idea to create new table "blc_product_tags", and add the tags to solr index. is my idea that correct?

I notice the documents of "Customizing and Extending SolrIndexService", but it is empty about this topic. Could you provide some guideline?

You must be checking the documentation of version 4.0. Refer documentation of previous versions. You can refer to load_catalog_data.sql in order to get an idea of how the entries are made in order to add facets and search fields.

Cheers
