Hi Cameron,

I've heard a few people recommending [b] Solr [a] for lightning fast
spatial search, which leads me to question my understanding of best
practice OGC / OSGeo design paradigms.
Solr is one of the most popular enterprise search engine, with NoSQL
features recently added.
Traditionally it is not used to replace a database but to create indexes
and make searches very fast.
In particular:
1. Have people been rolling out Solr's spatial search into production
instead of WFS (such as GeoServer)? Why was or was not Solr chosen?
Solr has been widely used in production as part of CKAN [1].
Specifically CKAN with spatial extension was deployed recently in US
data.gov [2], data.gov.uk [3] and data.gov.au [4] among others.
Two of the OSGeo CSW implementations are planning to support Solr as a
search back-end [5] [6]
2. Solr doesn't seem to follow OGC standards (I'd suspect a cut down
version of WFS would be appropriate). Are there discussions with the
OGC about setting up an appropriate standard which Solr could/should
follow?
3. If Solr is indeed a good match for certain use cases, then should
we be including it on OSGeo-Live [c]?
In my opinion we should consider CKAN (with spatial extension) to be
included in OSGeoLive.
[a] https://lucene.apache.org/solr/ Solr is the popular, blazing fast
open source enterprise search platform. Its major features include
powerful full-text search, hit highlighting, faceted search, near
real-time indexing, dynamic clustering, database integration, rich
document (e.g., Word, PDF) handling, and *geospatial search*.
