As Karsten said, providing more detail re what you're actually trying to do
usually makes for better and more helpful/accurate answers.
But I'm guessing you only want to search on the key, not the value, right?
If so, then:
1. Create a multi-value field with a custom type, indexed, stored.
2. During indexing, add entries as <key><tab><value>
3. In the custom type, set the analyzer to strip off the <tab><value> so you
only index the key. E.g.
<fieldType name="key_value" class="solr.TextField"
positionIncrementGap="100" autoGeneratePhraseQueries="true"
omitTermFreqAndPositions="true" omitNorms="true">
<analyzer type="index">
<!-- Get rid of <tab><value> text at the end of each string -->
<charFilter class="solr.PatternReplaceCharFilterFactory"
pattern="\t\d+$" replacement="" />
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1"
generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"
splitOnCaseChange="1"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1"
generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"
splitOnCaseChange="1"/>
</analyzer>
</fieldType>
