This is done both when indexing and when processing the query. See 
schema.xml in <analyzer type="index"> :

<filter class="solr.WordDelimiterFilterFactory"
	generateWordParts="1"
	generateNumberParts="1"
	catenateWords="1"
	catenateNumbers="1"
	catenateAll="0"
	splitOnCaseChange="1"
	preserveOriginal="1"
/>

splitOnCaseChange causes "camelCase" to be split into "camel" and "case".
