How to write custom component

[sivaprasad <si...@echidnainc.com>]

Hi,

I want to write a custom component which will be invoked before the query
parser.The out put of this component should go to the query parser.

How can i configure it in solrConfig.xml

How can i get SynonymFilterFactory object programmatically.

Please share your ideas.

Regards,
Siva

Probably best to start with http://wiki.apache.org/solr/SolrPlugins.  Also, have a look at the existing components, such as the TermsComponent or QueryComponent or SpellCheckComponent.

You might also want to consider explaining more what you are after (http://people.apache.org/~hossman/#xyproblem) before you go down the path.  Perhaps there is a way to do what you are after already?  Or perhaps you could just write a QParser that does what you need?

See the example, as it shows how to do it for the SpellCheckComponent.

You should be able to just construct one.
