float or string type for a field with whole number and decimal number values?
Hi I have a field that is of "int" type currentlyand it's values are whole numbers. stored="true" multiValued="false"/> Due tochange inbusiness requirement, this field will need to take in decimal numbers as well. This fieldis sorted onand filter by range (field:[ 1 to *]). Should I change the field type to "float" or "string"? For the change to take effect, do I need to delete all documents in the index and do a full indexing? Or I can just do a full indexing without theneed to delete all documents first?

Solr 6 CDCR does not work
I’m testing Solr 6 CDCR, but it’s seems not working.
Source configuration:
targetzkip:2181
corehol
corehol
1
1000
128
5000
${solr.ulog.dir:}
Target(s) configuration:
disabled
cdcr-proccessor-chain
${solr.ulog.dir:}
Source Log: no cdcr
Target Log: no cdcr
Create a core (solrconfig.xml modification directly from the folder
data_driven_schema_configs):
#bin/solr create -c corehol -p 8983
Start cross-data center replication by running the START command on the
source data center
http://sourceip::8983/solr/corehol/cdcr?action=START
Disable buffer by running the DISABLEBUFFER command on the target data
center
http://targetip::8983/solr/corehol/cdcr?action=DISABLEBUFFER
The documents are not replicated to the target zone.
What should I examine?
After Solr 5.5, mm parameter doesn't work properly
Hi, “mm" parameter does not work properly, when I set "q.op=AND” after Solr 5.5. In Solr 5.4, mm parameter works expectedly with the following setting. --- [schema] [request] http://localhost:8983/solr/collection1/select?defType=edismax&q.op=AND&mm=2&q=solar — After Solr 5.5, the result will not be the same as Solr 5.4. Has the setting of mm parameter specs, or description of file setting changed? [Solr 5.4] ... 2 solar edismax AND ... 0 solr solar solar (+DisjunctionMaxQuerytext:so text:ol text:la text:ar)~2/no_coord +(((text:so text:ol text:la text:ar)~2)) ... [Solr 6.0.1] ... 2 solar edismax AND ... solar solar (+DisjunctionMaxQuery(((+text:so +text:ol +text:la +text:ar/no_coord +((+text:so +text:ol +text:la +text:ar)) ... As shown above, parsedquery also differs from Solr 5.4 and Solr 6.0.1(after Solr 5.5). — Thanks Issei Nishigata

Thanks! I'll see to it. There're a lot to learn for CentOS, Geez.

Installing Solr:
https://cwiki.apache.org/confluence/display/solr/Taking+Solr+to+Production#TakingSolrtoProduction-RuntheSolrInstallationScript
Zookeeper is a completely separate project from Solr. For best results,
you should consult their documentation:
http://zookeeper.apache.org/doc/r3.4.8/zookeeperAdmin.html
I can give you some quick install steps based on what I have done in the
past. I have no idea whether this is how the zookeeper project would
recommend doing it, but if it's done correctly, I know that it works.
Extract the download tarball into some location, like /opt. If you
choose that location and extract the latest version, you will have
/opt/zookeeper-3.4.8 to work with. The rest of this assumes that
directory location. You may need to adjust these steps if you choose
another location:
Create a shell script named /usr/local/sbin/zkrun with these contents:
--
#!/bin/sh
# chkconfig: - 75 50
# description: Starts and stops Zookeeper
cd /opt/zookeeper
bin/zkServer.sh $1
--
Change to the /opt directory and do these commands:
ln -s zookeeper-3.4.8 zookeeper
chmod +x /usr/local/sbin/zkrun
ln -s /usr/local/sbin/zkrun /etc/init.d/zookeeper
chkconfig --add zookeeper
chkconfig zookeeper on
Consult zookeeper documentation on how to configure the newly installed
server -- which consists of creating /opt/zookeeper/conf/zoo.cfg and
${dataDir}/myid A common setting for the dataDir config parameter is
"zoodata". This is a path that is relative to the current working
directory. If you use my little startup script with that value, the
full path becomes opt/zookeeper/zoodata. Once it's configured, you can
start the zookeeper service. This is a slightly redacted copy of my
zookeeper config file:
-
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=zoodata
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=zoo1.REDACTED.com:2888:3888
server.2=zoo2.REDACTED.com:2888:3888
server.3=zoo3.REDACTED.com:2888:3888

Fw: SolrCloud and Zookeeper integration issue in .net application
Hi, This is my first time asking the question. I am facing some problems in Solr. Could you please help me out. Below is my question: Currently I am using Solr lower version it is working fine but now, we are trying to configure SolrCloud for load balance so, I have configured- 2 Solr nodes and 1 ZooKeeper node, created collections and shards also getting data from SQL server on Solr but i need to call SolrCloud in .net application. Please tell me, need to call zookeeper or SolrCloud and How it will configure in my .net application and what i need to configure it please help anyone. Warm Regards!

Re: SolrCloud and Zookeeper integration issue in .net application
Hi Shawn, Thank you for the reply. What I meant was that have configured Solr5.3 and Zookeeper 3.4.8. Currently using solrnet for Master and Slave concept but trying to use solr in cloud mode as mentioned previous and these clients doesn't have solution to talk to multiple solr server, I hope so. You have mentioned about load balancer please tell me what is load balancer (It is Hardware load balancer?) and how to configure on my machine for .net client. Thanks in advance. Warm Regards!

Please tell me, need to call zookeeper or SolrCloud and How it will configure in my .net application and what i need to configure it please help anyone. Unless you write the code to do it, a .net application will not know how to talk to zookeeper. There are multiple choices for .net clients which know how to talk to Solr via HTTP: https://wiki.apache.org/solr/IntegratingSolr#C.23_.2F_.NET I do not know if any of these clients know how to talk to multiple Solr servers so you don't have a single point of failure. If they don't, you will need a load balancer in front of your cloud. Solr itself will load balance the requests across the cloud, but if your application only talks HTTP to a single server:port, that instance of Solr becomes a single point of failure. For redundancy, you will need three zookeeper nodes: http://zookeeper.apache.org/doc/r3.4.8/zookeeperAdmin.html#sc_zkMulitServerSetup Thanks, Shawn
