Lower-cased string fieldtype?

I need a lower-cased string fieldtype (to use with the ElevationComponent),
but I'm temporarily stuck. The LowerCaseFilter needs a tokenizer, but I
don't want to tokenize. What am I missing?

KeywordTokenizer can help.

Thanks! I posted, went to get a sandwich, and came back to see two
answers. The change works, and I can get the fix into production today.
This list is magic.

RE: Lower-cased string fieldtype?

I'm not sure if I did this the right way but here's what I ended up
using:

<fieldType name="string" class="solr.TextField" sortMissingLast="true"
omitNorms="true">
	<analyzer>
		<tokenizer class="solr.KeywordTokenizerFactory"/>
		<filter class="solr.LowerCaseFilterFactory"/>
	</analyzer>
</fieldType>

According to the comments:

<!-- KeywordTokenizer does no actual tokenizing, so the entire input
string is preserved as a single token -->

Note: I had to use the TextField instead of StrField.

I need a lower-cased string fieldtype (to use with the
ElevationComponent),
but I'm temporarily stuck. The LowerCaseFilter needs a tokenizer, but I
don't want to tokenize. What am I missing?
