Solr 1.5 in production
What is the prevailing opinion on using solr 1.5 in a production
environment? I know that many people were using 1.4 in production for a
while before it became an official release.
Specifically I'm interested in using some of the new spatial features.
Thanks,
Asif

We're modeling hyperlocal news articles. Each article is indexed with a
shape that corresponds to the region of the map that is covered by the
source of the article. We considered modeling the locality of the articles
as points, but that approach would have limited our search options to
bounding box filters and slow distance calculations. We also felt that the
shape approach more closely resembled the true nature of the data. For now,
we're only using rectangles, but this approach will give us the ability to
index amorphous shapes as well. Are there any other techniques for indexing
shape data?

Yeah, I think in 1.5 you would use the subfield approach. How do you plan on using the shape in search?

One piece of functionality that I need is the ability to index a spatial
shape. I've begun implementing this for solr 1.4 using just the spatial
capabilities in lucene with a custom update processor and query parser. At
this point I'm only supporting rectangles and the shapes are being indexed
as sets of spatial tiles. In solr 1.5, I believe the correct implementation
would be as a field type with the new subfielding capabilities. Do you have
any thoughts about the approach I'm taking?

These aren't fully baked yet (still need some spatial filtering capabilities which I'm getting close to done with, or close enough to submit a patch anyway), but feedback would be welcome. The main risk, I suppose, is that any new APIs could change. Other than that, the usually advice applies: Test it out in your environment and see if it meets your needs. On the spatial stuff, we'd definitely appreciate feedback on performance, functionality, APIs, etc.
