indexing multiple schemas Vs extending existing schema

["Deo, Shantanu" <sd...@att.com>]

Hi,
  We have had some success in indexing our catalog proof-of-concept
project, Now we want to add information such as packages and accessories
which have a slightly different schema.

  I am wondering if its possible to add multiple indexes in the same
solr instance or should we think about redefining our existing schema
and trying to fit both our existing product data and the new data into
the same index.

  What are the pros and cons of either approach ? Has anyone had similar
situations before ? We would highly appreciate hearing your opinions
about this issue.

Sincerely

Hi,

If you don't need to search all of the data in a single query, use separate indices.  You don't need to run separate Solr instances - you can simply use Solr multi-core functionality.

Sticking different types of data into a single index and then searching only a subset could mess with your term frequency/weights and could affect your relevance score computation.

Thread Hijacking on Mailing Lists

When starting a new discussion on a mailing list, please do not reply to 
an existing message, instead start a fresh email.  Even if you change the 
subject line of your email, other mail headers still track which thread 
you replied to and your question is "hidden" in that thread and gets less 
attention.   It makes following discussions in the mailing list archives 
particularly difficult.
