Hello! When you don't specify a field or fields you want to search against, Solr will use the one set as the default in schema.xml file (the one defined with <defaultSearchField>).
So, you have the following field: <field name="text" type="text_en_splitting" indexed="true" stored="false" multiValued="true"/> When you don't specify copyField's this field won't have any values. So when searching without specifying the field name, Solr will send the query to the field named 'text' and because it is empty no results will be found. If you always want to search against the same set of fields, please take a look at the dismax or edismax query parsers, so you can make a query like: q=schedule a pickup&qf=Keywords Title TOC Overview where the qf specify the fields go be searched. -- Regards, Rafał Kuć > Rafał, > Thanks for your response. > I defined what I think you're referring to as "the default search field" as > <defaultSearchField>text</defaultSearchField> > I'm confused about how this works.
