Answer 1

Major Changes in schema.xml Solr 8.0 and 9.0 (Schema Changes in 8.0 and 9.0)

The following changes impact how fields behave.

Here is a table of solr deprecated fields and what is being used in solr 8.0

Deprecated	Instead Use
CurrencyField	CurrencyFieldType
EnumField	EnumFieldType
LatLonType	LatLonPointSpatialField
TrieDateField	DatePointField
TrieDoubleField	DoublePointField
TrieFloatField	FloatPointField
TrieIntField	IntPointField
TrieLongField	LongPointField
TrieField	This field takes a type parameter to define the specific class of Trie* field to use; Use an appropriate Point Field type instead.
LowerCaseTokenizer	You are encouraged to use the LetterTokenizer and the LowerCaseFilter instead

Note: Please make sure to re-index after changing any of the above for the changes to work and avoiding to get wired values.

Deprecated Field Types in Solr 9.0

Note: All Trie* numeric and date field types have been deprecated in favor of *Point field types. Point field types are better at range queries (speed, memory, disk), however simple field:value queries underperform relative to Trie. Either accept this, or continue to use Trie fields. This shortcoming may be addressed in a future release.

Deprecated	Instead Use
CurrencyField	CurrencyFieldType
EnumField	EnumFieldType
TrieDateField	DatePointField
TrieDoubleField	DoublePointField
TrieFloatField	FloatPointField
TrieIntField	IntPointField
TrieLongField	LongPointField
TrieField	This field takes a type parameter to define the specific class of Trie* field to use; Use an appropriate Point Field type instead.

Recommended Field Types are:

• BBoxField -> single rectangle
• BinaryField -> Binary data
• BoolField -> true or false
• CollationField -> Unicode Collation
• CurrencyFieldType -> Currencies and exchange rates.
• DateRangeField -> Date Formatting and Date Math
• DenseVectorField -> Dense Vector Search
• DatePointField -> Date field.
• DoublePointField -> Double field (64-bit IEEE floating point) and many more.. You can read more details here
