Solr example
------------

This directory contains Solr examples. Each example is contained in a 
separate directory. To run a specific example, do:

```
  bin/solr -e <EXAMPLE> where <EXAMPLE> is one of:
  
    cloud        : SolrCloud example
    schemaless   : Schema-less example (schema is inferred from data during indexing)
    techproducts : Kitchen sink example providing comprehensive examples of Solr features
```

For instance, if you want to run the SolrCloud example, do:

```
  bin/solr -e cloud
```

To see all the options available when starting Solr:

```
  bin/solr start -help
```

After starting a Solr example, direct your Web browser to:

```
  http://localhost:8983/solr/
```

To add documents to the index, use bin/post, for example:

```
     bin/post -c techproducts example/exampledocs/*.xml
```

(where "techproducts" is the Solr core name)

Notes About These Examples
--------------------------

### References to Jar Files Outside This Directory

Various example SolrHome dirs contained in this directory may use "<lib>"
statements in the solrconfig.xml file to reference plugin jars outside of 
this directory for loading "contrib" plugins via relative paths.  

If you make a copy of this example server and wish to use the 
ExtractingRequestHandler (SolrCell), the clustering component, 
or any other modules in "contrib", you will need to
copy the required jars or update the paths to those jars in your 
solrconfig.xml.

### Logging

By default, Jetty & Solr will log to the console and logs/solr.log. This can
be convenient when first getting started, but eventually you will want to
log just to a file. To configure logging, edit the log4j2.xml file in
".../server/resources".
It is also possible to setup log4j or other popular logging frameworks.
