Subject SOLR, Coveo, and Oracle questions
Date Wed, 18 Feb 2015 16:07:50 GMT

I have some basic questions for the group.  I would appreciate any advice
you can give me.

We have an Oracle RAC database that has a number of schemas on it.  Various
"things" query the structured data stored in these schemas, 10s of
thousands of times per day.  Two of these schemas in particular we wish to
replicate into a Lucene-based enterprise search environment.  This in total
will cover about 750 million "records" that span a few dozen tables in each

As I said, we have structured data here.  No documents, no BLOBS and no

We have front-end search tools already in place that provide the user with
filtering options that, when submitted by the user, run carefully optimized
(and indexed) dynamically-built queries against the data in these schemas.
These are on all the common fields you'd imagine when searching for user
data--name, etc.

As I said, we would like to replicate this data into a Lucene-based
environment and revise the front-end that formerly was hitting Oracle to
instead call RESTful APIs that we develop, to go against this new
Lucene-based tier.  We want to retain all of the previous faceted search
abilities, and not have anything run more slowly than before.  In addition
to retaining all of the existing filtering options for the user, we would
like to introduce an additional single google-style search window that
really takes advantage of the fancy new indexes and features that SOLR can

At this point I am trying to understand how the indexes work for structured
data in Lucene, and whether this is feasible to basically take all search
processing and querying out of Oracle.  Most of the Lucene/SOLR
documentation that I've found puts emphasis on all the great things it can
do with unstructured data, and does not address what it can do with
structured data.  Can anyone please give me some feedback or point me in
the right direction?

Second question-- members of our group are trying to sway us to using Coveo
Enterprise Search, another Lucene-based tool, rather than SOLR.  I realize
this is a SOLR forum, and I was hoping someone might be able to give some
insight as to why SOLR (or Coveo) would be the better option.  We will be
using custom written interfaces, so SOLR's out of the box search interfaces
would not be helpful to us.

Thanks for your time,
