Plugin discovery documentation contained information about installing Elasticsearch 2.0 and installing an oracle JDK, both of which is no longer valid. While noticing that the instructions used cleartext HTTP to install packages, this commit replaces HTTPs links instead of HTTP where possible. In addition a few community links have been removed, as they do not seem to exist anymore. Co-authored-by: Alexander Reelsen <alexander@reelsen.net>

== 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`>>.
