Hi Salman,
that's because you're using a StandardTokenizer. Try with something like
this (copied, pasted and changed using my phone so probably with a lot of
mistakes ;) but you should be able to get what I mean). BTW I don't know if
that's the case but I would also put a MappingCharFilterFactory
<fieldType name="text_suggestion" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
* <charFilter class="solr.MappingCharFilterFactory"
mapping="mapping-FoldToASCII.txt"/> *
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="0" generateNumberParts="0" catenateAll="1"
splitOnCaseChange="0" />
<filter class="solr.EdgeNGramFilterFactory"
maxGramSize="20"/>
</analyzer>
<analyzer type="query">
* <charFilter class="solr.MappingCharFilterFactory"
mapping="mapping-FoldToASCII.txt"/>*
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="0" generateNumberParts="0" catenateAll="1"
splitOnCaseChange="0" />
</analyzer>
</fieldType>
