Intermittent connection timeouts to Solr server using SolrNet
Hi - I have also posted this question on SO:
http://stackoverflow.com/questions/8741080/intermittent-connection-timeouts-to-solr-server-using-solrnet
I have a production webserver hosting a search webpage, which uses SolrNet
to connect to another machine which hosts the Solr search server (on a
subnet which is in the same room, so no network problems). All is fine >90%
of the time, but I consistently get a small number of The operation has
timed out errors.
I've increased the timeout in the SolrNet init to *30* seconds (!)
SolrNet.Startup.Init(
new SolrNet.Impl.SolrConnection(
System.Configuration.ConfigurationManager.AppSettings["URL"]
) {Timeout = 3}
);
...but all that happened is I started getting this message instead of Unable
to connect to the remote server which I was seeing before. It seems to have
made no difference to the amount of timeout errors.
I can see *nothing* in *any* log (believe me I've looked!) and clearly my
configuration is correct because it works most of the time. Anyone any
ideas how I can find more information on this problem?
Thanks!

Re: Unable to index documents using DataImportHandler with MSSQL
Hah, I've just come on here to suggest you do the same thing! Thanks
for getting back to me - and interesting we both came up with the same
solution!
Now I have the problem that running a delta update updates the
'dataimport.properties' file - but then just re-fetches all the data
regardless! Weird!

Right.
This is REALLY weird - I've now started from scratch on another

Re: Unable to index documents using DataImportHandler with MSSQL
Update on this: I've established:
* It's not a problem in the DB (I can index from this DB into a Solr
instance on another server)
* It's not Tomcat (I get the same problem in Jetty)
* It's not the schema (I have simplified it to one field)
That leaves SolrConfig.xml and data-config.
Only thing changed in SolrConfig.xml is adding:
D:/Software/Solr/example/solr/conf/data-config.xml
And data-config.xml is pretty much as attached - except simpler.
Any help or any advice on how to diagnose would be appreciated!

Unable to index documents using DataImportHandler with MSSQL
Hi I have copied my Solr config from a working Windows server to a new one, and it can't seem to run an import. They're both using win server 2008 and SQL 2008R2. This is the data importer config I can use MS SQL Profiler to watch the Solr user log in successfully, but then nothing. It doesn't seem to even try and execute the stored procedure. Any ideas why this would be working one server and not on another?

Solr 3.4 group.truncate does not work with facet queries
Hi, I'm using Grouping with group.truncate=true, The following simple facet query: facet.query=Monitor_id:[38 TO 40] Doesn't give the same number as the nGroups result (with grouping.ngroups=true) for the equivalent filter query: fq=Monitor_id:[38 TO 40] I thought they should be the same - from the Wiki page: 'group.truncate: If true, facet counts are based on the most relevant document of each group matching the query.' What am I doing wrong? If I turn off group.truncate then the counts are the same, as I'd expect - but unfortunately I'm only interested in the grouped results. - I have also asked this question on StackOverflow, here: http://stackoverflow.com/questions/7905756/solr-3-4-group-truncate-does-not-work-with-facet-queries Thanks! -- Ian i...@isfluent.com +44 (0)1223 257903
