Help needed in handling plurals

[taimurAQ <ta...@hotmail.com>]

Hi,

I am currently facing the following problematic scenario:

At index time, i index a field by the value of "Laptop"
At index time, i index another field with the value of "Laptops"
At query time, i search for "Laptops".

What is happening right now is that i am only getting back "Laptops" in the
results, whereas i would like both "Laptop" and "Laptops" to be included. I
do not want to use the Porter stemmer due to its aggressive nature, and i
have tried to set up Pling Stemmer as a custom filter in my analyzer, but,
to no avail.

Can anyone guide me as to:
1. Where to put the PlingStemmer.class file.
2. How to set up the custom filter in the schema.xml file.

Thanks in advance.

Regards,
Taimur

For an alternative to PlingStemmer see :
http://search-lucene.com/m/uHzMd2h5uDK1/

To integrate Pling to solr you need to write a custom TokenFilterFactory.
http://wiki.apache.org/solr/SolrPlugins

public class PlingStemFilterFactory extends BaseTokenFilterFactory {

}
You can do this by modifying existing subclasses.

You need to create a jar file and put it into solrhome/lib directory.
All custom codes must be included as jar files.
