struggling with solr.WordDelimiterFilterFactory and periods "." or dots

[geeky2]

hello all,

i am struggling with getting solr.WordDelimiterFilterFactory to behave as is
indicated in the solr book (Smiley) on page 54.

the example in the books reads like this:

>>
Here is an example exercising all options:
WiFi-802.11b to Wi, Fi, WiFi, 802, 11, 80211, b, WiFi80211b
<<

essentially - i have the same requirement with embedded periods and need to
return a successful search on a field, even if the user does NOT enter the
period.

i have a field, itemNo that can contain periods ".".

example content in the itemNo field:

B12.0123

when the user searches on this field, they need to be able to enter an
itemNo without the period, and still find the item.

example:

user enters: B120123 and a document is returned with B12.0123.


unfortunately, the search will NOT return the appropriate document, if the
user enters B120123.

however - the search does work if the user enters B12 0123 (a space in place
of the period).

can someone help me understand what is missing from my configuration?


this is snipped from my schema.xml file


  <fields>
     ...
    <field name="itemNo" type="text" indexed="true" stored="true"/>
     ...
