Scott Smerchek commented on SOLR-3676:
--------------------------------------
The goal here would be to have a case-insensitive id. Obviously, one could just
lowercase everything manually all the time as a workaround. However, this was
such unexpected behavior for an update that it definitely seems to be a bug.

> Components: update
> Affects Versions: 4.0-ALPHA
> Reporter: Scott Smerchek

> Given a schema of:
> {code}
> <field name="_version_" type="long" indexed="true" stored="true"/>
> <field name="id" type="lowercase" indexed="true" stored="true"
> required="true" />
> <dynamicField name="*" type="lowercase" indexed="true" multiValued="true"
> stored="true" />
> {code}
> and using the {{solr.UpdateRequestHandler}} and {{updateLog}}
> {code}
> <updateHandler class="solr.DirectUpdateHandler2">
> <updateLog>
> <str name="dir">{solr.core.home}/data</str>
> </updateLog>
> </updateHandler>
> {code}
> Adding the document:
> {code}
> {
> "id": "TEST",
> "someField": "SomeValue"
> }
> {code}
> and then adding the same document again with a new value
> {code}
> {
> "id": "TEST",
> "someField": "Some New Value"
> }
> {code}
> returns BOTH documents. It does not overwrite the original.
> {code}
> <result name="response" numFound="2" start="0">

> However, adding a document with a lowercase version of the id:

> {
> "id": "test",
> "someField": "Some NEWER Value"
