Momo,

if you have the conversion text to tokens then all you need to do is =
implement a custom analyzer, deploy it inside the solr webapp, then plug =
it into the schema.

Is that the part that is hard?
I thought the wiki was helpful there but may some other issue is holding =
you.
One zoology of such analyzers is at:
	http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters

If that is the issue, here's a one sentence explanation: if you have a =
new analyzer you want to declare a new field-type and field with that =
analyzer; queries should be going through it as well as indexing. =
Matching word A with word B will then happen if word A and B are =
converted by your analyzer to the same token (this is how cat and cats =
match when using the PorterStemmer for example).
