[Parameter] Field Type [Fields API Attribute Name] field_type [Description] 
The field type setting controls how a field is analyzed. There are many options available, and more can be added by adding a new plugin to the schema.xml file. It is crucial to understand the underlying values for a field in order to correctly set its type. For full text fields, such as "title", "body", or "description", a text field type is generally the desired setting so individual words in the text are searchable. There are various text field types, most of which are language-specific. However, when a text field value is to be taken literally as-is (exact match only, or for faceting), the "string" type is likely the right choice. There are also types for numeric data, including double, float, integer, and long (and variants of each suitable for sorting: sdouble, sfloat, sint, and slong). The date field accepts dates in the form "1995-12-31T23:59:59.999Z", with the fractional seconds optional, and trailing "Z" mandatory. Field types are defined in Solr's schema.xml file.
