Generally, stemming filters are not supported when wildcards are present.
Only a small subset of filters work with wildcards, such as the case
conversion filters.
But, you stay that you are using the stemmer to remove diacritical marks...
you can/should use ASCIIFoldingFilterFactory or MappingCharFilterFactory.

Hi all!
Sorry in advance if this question was posted but I were unable to find it
with search engines.
Filter SpanishLightStemFilterFactory is not working properly with wildcards
or I’m misunderstanding something. I have the field
<field name="cultivo_es" type="text_es" indexed="true" stored="true" />
With this type:
<fieldType name="text_es" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="lang/stopwords_es.txt" format="snowball" />
<filter class="solr.SpanishLightStemFilterFactory"/>
<!-- more aggressive: <filter
class="solr.SnowballPorterFilterFactory" language="Spanish"/> -->
</analyzer>
</fieldType>
But I’m getting these results:
q = cultivo_es:uva
Getting 50 correct results
q = cultivo_es:uva*
Getting the same 50 correct results
q = cultivo_es:naranja
Getting the 50 correct results of “naranja”
q = cultivo_es:naranja*
Getting the 0 results !!!!!!!!!
It works fine if I remove SpanishLightStemFilterFactory filter, but I need
it in order to filter diacritics according to Spanish rules.
Thank you!!
