Apache Configuration Question

Error undefined field: "language"

I have a project with apache solr (version 6.2) and tika. I configurate the schema.xml, data-config.xml and solrconfig.xml, but when I try to upload pdf with method \update\extract\ the log show me an error.

Answer

Check if schema.xml file is missing language field and its type definition. Add the language field into schema file. example :

<field name="language" type="text_english" indexed="true" stored="true"/>

field definition for text_english

<fieldType name="text_english" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_en.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
