Solr Version

2010-03-02 Thread Marc Wilson 
Hi,

This is probably a really dumb question, but how can I find out which version 
of Solr is currently running on my (Windows) system? I can't seem to find 
anything in the Solr Admin interface nor the TomCat Manager.

Thanks,

Marc

Re-index after Solr config file changed without restarting services

2010-03-03 Thread Marc Wilson 
Hi,

I am attempting to achieve what I believe many others have attempted in the 
past: allow an end user to modify a Solr config file through a custom UI and 
then roll out any changes made without restarting any services. Specifically, I 
want to be able to let the user edit the synonyms.txt file and after committing 
the changes, force Solr to re-index based on those changes without restarting 
Tomcat.

I have configured a Solr Master and Slave, each of which has a single core:


* http://master:8080/solr/core

* http://slave:8080/solr/core

The cores are defined in respective solr.xml files as:


 
  

  
 


Replication has been configured in the Master solrconfig.xml as follows:



startup
commit
startup
commit
schema.xml,${configDir}stopwords.txt,${configDir}elevate.xml,${configDir}synonyms.txt



and the Slave solrconfig.xml as:



  http://master:8080/solr/core/replication
  internal
  5000
  1
  username
  password
  00:00:20
 


At service startup, replication works fine. However, when a change is made to 
the synonyms.txt file and 
http://master:8080/solr/admin/cores?action=RELOAD&core=core is called neither 
the Master nor Slave are updated to reflect the modification. I am assuming 
that this is because in the Master schema.xml file the SynonymFilterFactory is 
being used at index time and the CoreAdmin RELOAD does not force a Solr 
re-index. If this is so, please can someone advise what the best methodology is 
to achieve what I am attempting? If not, please could someone let me know what 
I'm doing wrong?!

Thanks,

Marc
