Your field needs to use a field type which has a character folding/mapping
filter, such as:
<charFilter class="solr.MappingCharFilterFactory"
mapping="mapping-ISOLatin1Accent.txt"/>
Such as in:
<fieldType name="text_char_norm" class="solr.TextField"
positionIncrementGap="100" >
<analyzer>
<charFilter class="solr.MappingCharFilterFactory"
mapping="mapping-ISOLatin1Accent.txt"/>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
</analyzer>
</fieldType>
See the example schema.
In older releases of Solr there was an ISO Latin-1 filter and later the
"ASCII Folding Filter", but in 3.6 and trunk the above
MappingCharFilterFactory char filter is used.

Subject: Solr Filter for matching non-accented characters to their accented
equivalents
Hello,
Our company is maintaining a Vietnamese website and here is the problem:
Our keyboards do not contain accented characters... and once we search for a
product, our non-accented-character searches result to nothing. We need Solr
to match our non-accented characters to their accented character
equivalents. For example:
Searching for Tre Trung would contain results with the words Trẻ trung.
Really hope someone can help. Thanks!
