    <schema name="example core one" version="1.1">       <types>        <fieldtype name="string"  class="solr.strfield" sortmissinglast="true" omitnorms="true"/>         <fieldtype name="string_lowercase" class="solr.textfield" sortmissinglast="true" omitnorms="true">         <analyzer type="query">             <tokenizer class="solr.keywordtokenizerfactory"/>             <filter class="solr.lowercasefilterfactory"/>         </analyzer>     </fieldtype>        </types>       <fields>          <!-- general -->        <field name="id" type="string"    indexed="true"  stored="true"  multivalued="false" required="true"/>       <field name="issue" type="string_lowercase"    indexed="true"  stored="true"  multivalued="false" required="true"/>       <field name="suggestion" type="string_lowercase" indexed = "true" stored="true" multivalued="false" required = "true"/>       <field name="title" type="string_lowercase" indexed = "true" stored="true" multivalued="false" required = "true"/>       <field name="company_id" type="string" indexed = "true" stored="true" multivalued="false" required = "true"/>       <field name="company_name" type="string_lowercase" indexed = "true" stored="true" multivalued="false" required = "true"/>       <field name="company_logo" type="string" indexed = "true" stored="true" multivalued="false" required = "false"/>       </fields>         <!-- field use determine , enforce document uniqueness. -->      <uniquekey>id</uniquekey>       <!-- field queryparser use when explicit fieldname absent -->      <defaultsearchfield>title</defaultsearchfield>       <!-- solrqueryparser configuration: defaultoperator="and|or" -->      <solrqueryparser defaultoperator="or"/>     </schema>*

try remove required= "false" attribute in field (it should default anyway).

try change definition of field this: 

<field name="company_logo" type="string" indexed = "true" stored="true" multivalued="false"/>
