Hello guys,
Hey, I think I´ve found how to do this just adding a filter. Just for
anyone´s curiosity:
<fieldType name="emails" class="solr.TextField" sortMissingLast="true"
omitNorms="true">
<analyzer>
<tokenizer class="solr.UAX29URLEmailTokenizerFactory"/>
<filter class="solr.TypeTokenFilterFactory" types="email_type.txt"
useWhitelist="true"/>
</analyzer>
</fieldType>
Anyway, I still need to do a query like the following to retrieve those
documents with at least one E-mail detected:
http://localhost:8080/mysolr/select?q=emails:[* TO
*]&start=0&rows=10&sort=mydate desc
And I don´t like it, to be honest,
Regards,
