problems with search in solr

Good morning:
I have problems with the results obtained Solr search string (eg caso). Me back records with similar terms (in this example would return the same as if looking casa).
The 1.4.1 version of Solr is
The definition of type text in the file schema.xml is:



<fieldtype name="text" class="solr.TextField">

  <analyzer>

    <charFilter class="solr.HTMLStripCharFilterFactory"/>

    <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>

    <tokenizer class="solr.StandardTokenizerFactory"/>

    <filter class="solr.LowerCaseFilterFactory"/>

    <filter class="solr.StopFilterFactory"/>

    <filter class="solr.PorterStemFilterFactory"/>

  </analyzer>

</fieldtype>


Could you tell if an error in the configuration and how to solve it.

thanks

Or if you still want to have stemming, you could use a Spanish stemmer,
like:

<filter class="solr.SnowballPorterFilterFactory" language="Spanish"/>
or
<filter class="solr.SpanishLightStemFilterFactory"/>

Remove the stemmer filter. "Caso" and "casa" are transformed into "cas" if you use the stemmer filter.

En español:
Quita el filtro de stemmer, que se usa para sacar la raiz de las palabras, pero en tu caso la raíz de "casa" y "caso" es la misma, "cas".

Un saludo.

Hello!

The probable cause is the use of solr.PorterStemFilterFactory. You can check it using the Solr admin or by removing that filter and reindexing your data.
