Solr is one of the most popular enterprise search engine, with NoSQL
features recently added. <br>
Traditionally it is not used to replace a database but to create
indexes and make searches very fast.<br>

In particular:

<br>
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?
<br>

<br>
Solr has been widely used in production as part of CKAN [1].<br>
Specifically CKAN with spatial extension was deployed recently in US
data.gov [2], data.gov.uk [3] and data.gov.au [4] among others.<br>
<br>
Two of the OSGeo CSW implementations are planning to support Solr as
a search back-end [5] [6]<br>

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?
<br>
<br>
<br>
3. If Solr is indeed a good match for certain use cases, then
should we be including it on OSGeo-Live [c]?
<br>

<br>
In my opinion we should consider CKAN (with spatial extension) to be
included in OSGeoLive.<br>

[a] <a class="moz-txt-link-freetext" href="https://lucene.apache.org/solr/">https://lucene.apache.org/solr/</a> 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*.
