I am a computer geek with interest in Java, C#, and Apache Solr, business models, visualization and whatever else catches my fancy.

I wrote a book on Solr: http://bit.ly/ZPSSt4 and maintain useful Solr resources at http://www.solr-start.com/

comment Solr query syntax. is "range:[1000 to 1000]" equal to "range:1000"?
Range search might be a bit slower. Since it is a more complex algorithm.

comment How does one write maintainable Solr code?
It is all over the examples. If you read schema.xml, it shows all the interesting things you can learn (e.g. dynamicField *, commented out). You just need to give it time, as the examples have grown and became quite large over time.

comment haystack is unable to connect to solr search engine
Can you connect to the same Solr from the other machine? If yes, you definitely have something wrong on this machine. I would try just running a Vanilla server on a different machine and see if you can connect to that. And you definitely don't need collection name in the URL? I don't know haystack that well.

comment Solr suddenly shutsdown gracefully
How do you start the Solr? Is it a service? If so, you must have a definition somewhere (init.d?). Check that. The other things to try is to change the STOP port number or to run network and/or process trace over the 5 minutes spinning the shutdown. Basically, this should not be happening normally, so it has to be something interesting on your system.

comment Apache Solr suggester dictionary is not updated after removing some records from collection
The 'deleted' but not 'merged/purged' records is a deep part of Lucene implementation and does sometimes affect less obvious parts of the system. I have added the comment to the documentation page for this to be reviewed and - if correct - mentioned: cwiki.apache.org/confluence/display/solr/Spell+Checking

comment Solr suddenly shutsdown gracefully
Sounds like a Cron job or perhaps an invalid service definition. Nothing else can explain this happening multiple times precisely at midnight. I would check those two.

comment haystack is unable to connect to solr search engine
sorry, it is telnet 127.0.0.1 8983 with the space for the port. It should tell you "connecting to port 23". Still, check your browser configurations. Maybe there is a misconfigured proxy somewhere. Also try using localhost instead of 127.0.0.1. Should be identical but something is obviously wrong.

comment Apache Solr suggester dictionary is not updated after removing some records from collection
This sounds like perhaps spellchecker ignores the deleted flag. The records are not truly deleted until the segments are merged (e.g. with - not recommended - optimize call, or by hitting the merge threshold) or if all the records in a segment are deleted and the whole segment can be dropped. Do an experiment. Add other two records, commit. Add your test record, commit. Check it shows up in spelling. Delete just that test record and commit. If it disappears from the spelling, than my assumption is right. Either way, this might be worth taking to the Solr Users mailing list.
