Hello

Consider this scenario:

  * 3 servers, 3 databases, each on a separate server:
      o *Products database*: Contains the *Products* table (with over
        100,000 records).
      o *Taxonomy database*: Contains the *Categories* and
        *ItemCategories (EAV)* tables.
      o *Attributes database*: Contains the *Attributes* and
        *ItemAttributes (EAV)* tables.

How do you find products based on the following criteria?

 1. A search in the title (e.g., "awesome shirts").
 2. Selected categories (e.g., "casual" and "sports").
 3. Selected attributes (e.g., "color: blue" and "size: large")
