Update allocation awareness docs
Today, the docs imply that if multiple attributes are specified the the
whole combination of values is considered as a single entity when
performing allocation. In fact, each attribute is considered separately. This
change fixes this discrepancy.
It also replaces the use of the term "awareness zone" with "zone or domain", and
reformats some paragraphs to the right width.
Fixes#29105
This is a follow up to a previous change which set the error file path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to the root of the
installation (i.e., Elasticsearch home). Therefore, we can specify the
error file path relative to this directory and default it to the logs
directory, similar to the package distributions.
This is a follow up to a previous change which set the heap dump path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to to the root of
installation (i.e., Elasticsearch home). Therefore, we can specify the
heap dump path relative to this directory and default it to the data
directory, similar to the package distributions.
Adds support for triple quoted strings to the documentation test
generator. Kibana's CONSOLE tool has supported them for a year but we
were unable to use them in Elasticsearch's docs because the process that
converts example snippets into tests couldn't handle this. This change
adds code to convert them into standard JSON so we can pass them to
Elasticsearch.
I have seen this question a couple times already, most recently at
https://twitter.com/dimosr7/status/973872744965332993
I tried to keep the explanation as simple as I could, which is not always easy
as this is a matter of trade-offs.
Additionally:
* Included the existing update by query java api docs in java-api docs.
(for some reason it was never included, it needed some tweaking and
then it was good to go)
* moved delete-by-query / update-by-query code samples to java file so
that we can verify that these samples at least compile.
Closes#24203
The Java API documentation for index administration currenty is wrong because
the PutMappingRequestBuilder#setSource(Object... source) an
CreateIndexRequestBuilder#addMapping(String type, Object... source) methods
delegate to methods that check that the input arguments are valid key/value
pairs. This changes the docs so the java api code examples are included from
documentation integration tests so we detect compile and runtime issues earlier.
Closes#28131
By the time the master branch is released the deprecated url
parameters in the `/_cache/clear` API will have been deprecated
for a couple of minor releases. Since master will be the next
major release we are fine with removing these parameters.
Currently we have a fairly complicated logic in the engine constructor logic to deal with all the
various ways we want to mutate the lucene index and translog we're opening.
We can:
1) Create an empty index
2) Use the lucene but create a new translog
3) Use both
4) Force a new history uuid in all cases.
This leads complicated code flows which makes it harder and harder to make sure we cover all the
corner cases. This PR tries to take another approach. Constructing an InternalEngine always opens
things as they are and all needed modifications are done by static methods directly on the
directory, one at a time.
We today support a global `indexed_chars` processor parameter. But in some cases, users would like to set this limit depending on the document itself.
It used to be supported in mapper-attachments plugin by extracting the limit value from a meta field in the document sent to indexation process.
We add an option which reads this limit value from the document itself
by adding a setting named `indexed_chars_field`.
Which allows running:
```
PUT _ingest/pipeline/attachment
{
"description" : "Extract attachment information. Used to parse pdf and office files",
"processors" : [
{
"attachment" : {
"field" : "data",
"indexed_chars_field" : "size"
}
}
]
}
```
Then index either:
```
PUT index/doc/1?pipeline=attachment
{
"data": "BASE64"
}
```
Which will use the default value (or the one defined by `indexed_chars`)
Or
```
PUT index/doc/2?pipeline=attachment
{
"data": "BASE64",
"size": 1000
}
```

* Add a REST integration test that documents date_range support
Add a test case that exercises date_range aggregations using the missing
option.
Addresses #17597
* Test cleanup and correction
Adding a document with a null date to exercise `missing` option, update
test name to something reasonable.
* Update documentation to explain how the "missing" parameter works for
date_range aggregations.
* Wrap lines at 80 chars in docs.
* Change format of test to YAML for readability.
The current docs on [Indices APIs: PUT Mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html) suggests that a having number of different mapping types per index is still possible in elasticsearch versions > 6.0.0 although they have been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html). The console code has already been updated accordingly but notes (2) and (3) on the console code still name the `user` mapping type.
This PR updates the list with notes after the console code, as well as the first sentence of the docs
to avoid confusion. Also, I have removed the second command from the console code as it no
longer holds any value if the docs are solely on the `_doc` mapping.
The docs state that `_gce_` is recommended but the code sample states
that `_gce:hostname_` is recommended. This aligns the code sample with
the documentation. Also replace `type` with `zen.hosts_provider` as
discovery.type was removed in #25080.
With this commit we reduce heap usage of the ingest-geoip plugin by
memory-mapping the database files. Previously, we have stored these
files gzip-compressed but this has resulted that data are loaded on the
heap.
Closes#28782
The original example resulted in a 400 error due to the example being `-` separated instead of the default `.` separation.
```
failed to parse date field [2001-01-01] with format [YYYY.MM.dd]
```
Adds a usage example of the JLH score used in significant terms aggregation.
All other methods to calculate significance score have such an example
Closes#28513
Increase the default limit of `index.highlight.max_analyzed_offset` to 1M instead of previous 10K.
Enhance an error message when offset increased to include field name, index name and doc_id.

* Clarifies how the query_string splits textual part to build a query
Whitespaces are not considered as operators anymore in 6x but the documentation is not clear about it.
This commit changes the example in the documentation and adds a note regarding whitespaces and operators.
