solr LowerCaseFilterFactory should not filter number

I'm using a query schema which need to let abc match Abc and 400 match 400 (user name match).

But I found when I use LowerCaseFilterFactory, It not return any result when I query 400. I digg into the source code, and found LowerCaseTokenizerFactory use LowerCaseTokenizer which extends LetterTokenizer, and it filter all the numbers.

How should I fix this?

You are right that LowerCaseTokenizer will remove all non-letters. It would very useful (as far as providing a meaningful answer) to see your schema, as I don't believe just using the lowercase filter factory should generate a Tokenizer of any kind.

At any rate, though, there are plenty of other options for tokenizers. Both Standard or Classic might suit your needs better.

Something along the line of:

<analyzer>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>

Might do well for you.
