Solr returned an error #400 (Bad Request) for url
I am using Solr 6.5.0, and I came across a scenario where I have to index a data field which may of multiple languages in the document.
I am trying to use a separate field for each language and I have to index the data of specific language to the corresponding field defined for that language.
I have added below config and schema changes:
Solr config:
<requestHandler name="/update" class="solr.UpdateRequestHandler">
<lst name="defaults">
<str name="update.chain">langid</str>
</lst>
</requestHandler>
<updateRequestProcessorChain name="langid">
<processor class="org.apache.solr.update.processor.TikaLanguageIdentifierUpdateProcessorFactory">
<str name="langid.fl">title</str>
<str name="langid.langField">lang</str>
<str name="langid.fallback">en</str>
</processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
schema:
<field name="code" type="string" indexed="true" stored="true"/>
<field name="title" type="string" indexed="true" stored="true"/>
<field name="content_english" type="text_english" indexed="true" stored="true"/>
<field name="content_french" type="text_french" indexed="true" stored="true"/>
<field name="content_spanish" type="text_spanish" indexed="true" stored="true"/>
Input xml:
<add>
<doc>
<field name="code">one</field>
<field name="title">Adventures</field>
<field name="content_english">Especially the fuzzy search is very welcome; Solr really is a beautiful engine and it’s incredibly fast: millions of documents are no problem. Of course, if your servers capacities are configured correctly.</field>
</doc>
<doc>
<field name="code">two</field>
<field name="title">Aventures</field>
<field name="content_french">Surtout la recherche floue est très bienvenue; Solr est vraiment un beau moteur et c'est incroyablement rapide: des millions de documents ne posent aucun problème. Bien sûr, si les capacités de vos serveurs sont configurées correctement.</field>
</doc>
<doc>
<field name="code">three</field>
<field name="title">Aventuras</field>
<field name="content_spanish">Especialmente la búsqueda difusa es muy bienvenida; Solr realmente es un motor hermoso y es increíblemente rápido: millones de documentos no son ningún problema. Por supuesto, si las capacidades de los servidores están configuradas correctamente.</field>
</doc>
</add>
whenever I update the core, I'am getting the below error:

Error : ID field is missing from your documents.
id which is used to identify each document uniquely is specified in schema file like below.
<uniqueKey>id</uniqueKey>
Every document must and should have field which specified as uniquekey.
Include Id field for all your docs and check. ex:
<doc>
<field name="id">001</field>
<field name="code">one</field>
<field name="title">Adventures</field>
<field name="content_english">Especially the fuzzy search is very welcome; Solr really is a beautiful engine and it’s incredibly fast: millions of documents are no problem. Of course, if your servers capacities are configured correctly.</field>
</doc>
Well have you looked at the error? Your documents don't have a value for the mandatory field called 'id'. You either have to give each one an id:
<add>
<doc>
<field name="code">one</field>
<field name="id">1</field>
<field name="title">Adventures</field>
<field name="content_english">Especially the fuzzy search is very welcome; Solr really is a beautiful engine and it’s incredibly fast: millions of documents are no problem. Of course, if your servers capacities are configured correctly.</field>
</doc>
<doc>
<field name="code">two</field>
<field name="id">2</field>
<field name="title">Aventures</field>
<field name="content_french">Surtout la recherche floue est très bienvenue; Solr est vraiment un beau moteur et c'est incroyablement rapide: des millions de documents ne posent aucun problème. Bien sûr, si les capacités de vos serveurs sont configurées correctement.</field>
</doc>
<doc>
<field name="code">three</field>
<field name="id">3</field>
<field name="title">Aventuras</field>
<field name="content_spanish">Especialmente la búsqueda difusa es muy bienvenida; Solr realmente es un motor hermoso y es increíblemente rápido: millones de documentos no son ningún problema. Por supuesto, si las capacidades de los servidores están configuradas correctamente.</field>
</doc>
</add>
Or you can configure Solr to automatically assign a value if one isn't present.
