Search on Partial keywords

Hi,
I am using solr for my faceted search implementation. It is an e-commerce
site and the facets are based on product attributes.

I have added product code to my index. The search works well if the user
enters the complete product code. However if some one enters a partial code,
the search is failing. 

For example, if the product code is ABD019T, if the user enters ABD0 or
ABD01 or ABD019 the search fails to bring any results. But the search for
ABD brings the correct result.

Could you please let me know why I am seeing this behaviour?

Thanks in Advance.

Regards,
Raja

        <filter
class="uk.co.portaltech.quicklive.facet.spellcheck.analyzer.QuickLiveSynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="false"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory"

Let's see the schema definitions for the field in question and
query handler. I suspect that your indexing process is
splitting the word on the letter-number transitions but your
query processing isn't (WordDelimiterFactory?), but that's
only a guess in the absence of any data......
