Spatial / Local Solr radius
Hi everyone,
I'm getting inconsistent behavior from Spatial Solr when searching with
different radii. For the same lat/long I get:
radius=1 -> 1 result
radius=10 -> 0 result
radius=25 -> 2 results
radius=100 -> 2 results
radius=250 -> 0 results
I don't understand why radius=10 and 250 return no results. Is this a known
bug? I'm using the default configuration as specified in the PDF.
BTW I also tried LocalSolr with the same results.
Thanks
Mauricio

Mauricio,
I hooked up the spatial solr plugin to the Eclipse debugger and
narrowed the problem down to CartesianShapeFilter.getBoxShape(). The
algorithm used in the method can produce values of startX that are
greater than endX depending on the tier level returned by
CartesianTierPlotter.bestFit(). In this case, the "for" loop is
skipped altogether and the method returns a CartesianShape object with
an empty boxIds list.
I notice the problem when I have small, geographically sparse datasets.
I'm going to shoot the jteam an email regarding this.

Re: Spatial / Local Solr radius

Hi Michael
I exchanged a few mails with jteam, ultimately I realized my longitudes'
signs were inverted so I was mapping to China instead of U.S. Still a bug,
but inverting those longitudes "fixed" the problem in my case since I'm not
running world-wide searches.
Before that I ran a test to determine what radii failed for a grid of 3x3
lat/long with radius between 10 and 2500, if you're interested I can send
you the results to compare.
Also I'm running RC3, I see RC4 is out but haven't tried it.
It would be interesting to see if this happens with the new spatial
functions in trunk.

Mauricio,
I was wondering whether you had heard anything back from jteam
regarding this issue. I have also noticed it and was wondering why It
was happening.
One thing I noticed is that this problem only appears for "sparse"
datasets as compared to "dense" ones. For example, I have two datasets
I've been testing with - one with 56 U.S. cities (the "sparse" set)
and one with over 197000 towns and cities (the "dense" set). The dense
set exhibited no problems with consistency searching at various radii,
but the sparse set exhibited the same issues you experienced.

It's jteam's plugin ( http://www.jteam.nl/news/spatialsolr ) which AFAIK is
just the latest patch for SOLR-773 packaged as a stand-alone plugin.
I'll try to contact jteam directly.

What's QParser is the "spatial" plugin? I don't know of any such QParser in Solr. Is this a third party tool? If so, I'd suggest asking on that list.

When changing the radius to 250 I get no results.
In my config I have startTier = 9 and endTier = 17 (default values)

I faced the same problem when i used locallucene 1.5 and localsolr 1.5.
Now I am using localsolr 2.0 and locallucene 2.0 and I dont see that issue.
You need to upgrade the binaries.
