30. SOLR-940: Add support for Lucene's Trie Range Queries by providing new FieldTypes in schema for int, float, long,
|
||||
double and date. Range searches and term queries on such fields will automatically use the corresponding trie
|
||||
range filter in Lucene contrib-queries and can be dramatically faster than normal range queries.

<!--
|
||||
Numeric field types that manipulate the value into trie encoded strings which are not
|
||||
human readable in the internal form. Range searches on such fields use the fast Trie Range Queries
|
||||
which are much faster than range searches on the SortableNumberField types.
|
||||
|
||||
For the fast range search to work, trie fields must be indexed. Trie fields are <b>not</b> sortable
|
||||
in numerical order. Also, they cannot be used in function queries. If one needs sorting as well as
|
||||
fast range search, one should create a copy field specifically for sorting. Same workaround is
|
||||
suggested for using trie fields in function queries as well.
|
||||
|
||||
For each number being added to this field, multiple terms are generated as per the algorithm described in
|
||||
org.apache.lucene.search.trie package description. The possible number of terms depend on the precisionStep
|
||||
attribute and increase dramatically with higher precision steps (factor 2**precisionStep). The default
|
||||
value of precisionStep is 8.
|
||||
|
||||
Note that if you use a precisionStep of 32 for int/float and 64 for long/double, then multiple terms
|
||||
will not be generated, range search will be no faster than any other number field,
|
||||
but sorting will be possible.
