== Term-level queries
|
|
|
|
You can use **term-level queries** to find documents based on precise values in
|
|
structured data. Examples of structured data include date ranges, IP addresses,
|
|
prices, or product IDs.
|
|
|
|
Unlike <<full-text-queries, full-text queries>>, term-level queries do not
|
|
analyze search terms. Instead, term-level queries match the exact terms stored
|
|
in a field.
|
|
|
|
|
|
[NOTE]
|
|
====
|
|
Term-level queries still normalize search terms for `keyword` fields with the
|
|
`normalizer` property. For more details, see <<normalizer, `normalizer`>>.
