Uninstall Solr

Hi All,

How to *uninstall* Solr completely ?

Any help will be appreciated.

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 :)

[ANNOUNCE] Apache Solr 3.3

July 2011, Apache Solr™ 3.3 available
The Lucene PMC is pleased to announce the release of Apache Solr 3.3.

Solr is the popular, blazing fast open source enterprise search platform from
the Apache Lucene project. Its major features include powerful full-text
search, hit highlighting, faceted search, dynamic clustering, database
integration, rich document (e.g., Word, PDF) handling, and geospatial search.
Solr is highly scalable, providing distributed search and index replication,
and it powers the search and navigation features of many of the world's
largest internet sites.

This release contains numerous bug fixes, optimizations, and
improvements, some of which are highlighted below.  The release
is available for immediate download at:
   http://www.apache.org/dyn/closer.cgi/lucene/solr (see note below).

See the CHANGES.txt file included with the release for a full list of
details as well as instructions on upgrading.

Solr 3.3 Release Highlights

 * Grouping / Field Collapsing

 * A new, automaton-based suggest/autocomplete implementation offering an
   order of magnitude smaller RAM consumption.

 * KStemFilterFactory, an optimized implementation of a less aggressive
   stemmer for English.

 * Solr defaults to a new, more efficient merge policy (TieredMergePolicy).

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

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).
