Completely lost with Lucene

[321los]

Hi,

I'd like to use the Lucene search in my page, but reading the docs at http://cocoon.apache.org/2.1/userdocs/concepts/xmlsearching.html and http://wiki.apache.org/cocoon/LuceneIndexTransformer does not really enlighten me.

My case:
The content of my pages is generated dynamically, getting the data from a mysql database. Something like that,

<map:match pattern="karte">
    <map:generate type="file" src="">    <map:transform type="sql">
        <map:parameter name="use-connection" value="mysql-pool"/>
        <map:parameter name="lfdnr" value="{request-param:lfdnr}"/>
     </map:transform>
     <map:transform src="">     <map:serialize type="html"/>
</map:match>

So calling e.g. the address http://localhost:8080/cocoon/karte?lfdnr=412 shows me the results of the page with the sql primary key 412 transformed via style.xsl.

Lucene should be able to index the columns 'lfd_nr', 'venue' and 'description' (without indexing the other 6 columns of the table) and should give me the results, if those fields match my search query obviously, like shown above ( http://localhost:8080/cocoon/karte?lfdnr='pk')

Declaring the LuceneIndexTransformer of my sitemap is the only thing I have completely understood from the wiki. ;)
A little guidance would be appreciated very much. (+ what to write in which files, since that does not always emanate from the wiki)

Thanks in advance
Marco
