solr - searching part of words

Question

My field is defined as

<field name="PackageName" type="text_en" indexed="true" stored="true" required="true"/>

*text_en is defined as in the original schema.xml that comes with solr

Now, my field has the following vaues

• "one"
• "one1"

searching for "one" returns only the field "one". What causes it? how can I change it?

Answer 1

If you want to match the words from an alphanumeric indexed term, you may want to check for the WordDelimiterFilterFactory.
WordDelimiterFilterFactory allows splitOnNumerics which would allow One1 to be divided into One and 1 tokens and hence matching the Searched term One.
You can always preserveOriginal to match One1 as well.
