Re: Taxonomy faceting

Re: Uninstall Solr

How'd you install it?

Generally you just delete the directory where you "installed" it.  But you might be deploying solr.war in a
container somewhere besides Solr's example Jetty setup, in which case you need to undeploy it from those
other containers and remove the remnants.

Curious though... why uninstall it?  Solr makes a mighty fine hammer to have around :)

Re: Solr Clustering For Multiple Pages

Hi  

I am asking about the  filter after clustering . Faceting   is based on the
single field so,if we need to filter we can search in related field .  But
in clustering it is created by multiple field  then how can we create a
filter for that.

Example 

after clusetring you get the following  

Model(20)
System(15)
Other Topics(5)

if i will click on Model then i should get  record associated with Model

Regards
Nilay Tiwari

I'm not sure what you mean by "filter" -- ids of documents belonging to each
cluster are part of the response, see the "docs" array inside the cluster
(see http://wiki.apache.org/solr/ClusteringComponent#Quick_Start for example
output). When the user clicks a cluster, you just need to show the documents
with ids specified inside the cluster the user clicked.

Re: Multicore clustering setup problem

I'd probably need to take a look at the whole Solr dir you're working with,
clearly there's something wrong with the classpath of core1.

Again, I'm wondering if perhaps since both cores have the clustering

I'm not an expert on Solr's internals related to core management, but I once
did configure two cores with search results clustering, where clustering
configuration and <lib>s were specified for each core separately, so this is
unlikely to be a problem. Another approach would be to put all the JARs
required for clustering in a common directory and point Solr to that lib
using the sharedLib attribute in the <solr> tag:
http://wiki.apache.org/solr/CoreAdmin#solr. But it really should work both
ways.

Re: How to use solr clustering to show in search results

The "docs" array contained in each cluster contains ids of documents
belonging to the cluster, so for each id you need to look up the document's
content, which comes earlier in the response (in the response/docs array).

Cheers,
