Some source files seem to have the execute bit (a+x) set, which doesn't
really seem to hurt but is a bit odd. This change removes those, making
the permissions similar to other source files in the repository.
This change refactors the composite aggregation to add an execution mode that visits documents in the order of the values
present in the leading source of the composite definition. This mode does not need to visit all documents since it can early terminate
the collection when the leading source value is greater than the lowest value in the queue.
Instead of collecting the documents in the order of their doc_id, this mode uses the inverted lists (or the bkd tree for numerics) to collect documents
in the order of the values present in the leading source.
For instance the following aggregation:
```
"composite" : {
"sources" : [
{ "value1": { "terms" : { "field": "timestamp", "order": "asc" } } }
],
"size": 10
}
```
... can use the field `timestamp` to collect the documents with the 10 lowest values for the field instead of visiting all documents.
For composite aggregation with more than one source the execution can early terminate as soon as one of the 10 lowest values produces enough
composite buckets. For instance if visiting the first two lowest timestamp created 10 composite buckets we can early terminate the collection since it
is guaranteed that the third lowest timestamp cannot create a composite key that compares lower than the one already visited.
This mode can execute iff:
* The leading source in the composite definition uses an indexed field of type `date` (works also with `date_histogram` source), `integer`, `long` or `keyword`.
* The query is a match_all query or a range query over the field that is used as the leading source in the composite definition.
* The sort order of the leading source is the natural order (ascending since postings and numerics are sorted in ascending order only).
If these conditions are not met this aggregation visits each document like any other agg.
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.
* 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.
This reverts commit f057fc294a.
The rescorer does not resort the collapsed values inside the top docs
during rescoring. For this reason the Lucene rescorer is not compatible
with collapsing.
Relates #27243
* Reject regex search if regex string is too long (#28344)
* Add docs
* Introduce index level setting `index.max_regex_length`
to control the maximum length of the regular expression
Closes#28344
We added a rest test for the translog last modified age without a
version check. This causes BWC failed because the stats are not
available in the old versions.
Relates #28613
Currently the Translog constructor is capable both of opening an existing translog and creating a
new one (deleting existing files). This PR separates these two into separate code paths. The
constructors opens files and a dedicated static methods creates an empty translog.
Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
This adds the ability to index term prefixes into a hidden subfield, enabling prefix queries to be run without multitermquery rewrites. The subfield reuses the analysis chain of its parent text field, appending an EdgeNGramTokenFilter. It can be configured with minimum and maximum ngram lengths. Query terms with lengths outside this min-max range fall back to using prefix queries against the parent text field.
The mapping looks like this:
"my_text_field" : {
"type" : "text",
"analyzer" : "english",
"index_prefix" : { "min_chars" : 1, "max_chars" : 10 }
}
Relates to #27049
This change adds the `after_key` of a composite aggregation directly in the response.
It is redundant when all buckets are not filtered/removed by a pipeline aggregation since in this case the `after_key` is always the last bucket
in the response. Though when using a pipeline aggregation to filter composite buckets, the `after_key` can be lost if the last bucket is filtered.
This commit fixes this situation by always returning the `after_key` in a dedicated section.
This commit adds the ability to specify a date format on the `date_histogram` composite source.
If the format is defined, the key for the source is returned as a formatted date.
Closes#27923
MixedClusterClientYamlTestSuiteIT sometimes fails when executing the
indices.stats/13_fields/* REST tests. It does not reproduce locally
but the execution logs show that it failed when a shard is relocating
during the set up execution. This commit change the set up so that it
now waits for all shards to be active before executing the tests.
closes#26732, #27146
Currently when adding a document with a `null` value for a range field,
the range field mapper raises an error. Instead we should ignore null like
we do eg. with numbers or geo points.
Closes#27845
Java 9 added some enhancements to the internationalization support that
impact our date parsing support. To ensure flawless BWC and consistent
behavior going forward Java 9 runtimes requrie the system property
`java.locale.providers=COMPAT` to be set.
Closes#10984
- Introduce index level settings to control the maximum number of terms
that can be used in a Terms Query
- Throw an error if a request exceeds this max number
Closes#18829
This change fixes a bug when a keyword term in the `after` key is not present in the shard.
In this case the global ord of the document values are compared with the insertion point of the
`after` keyword and values that are equal to the insertion point should be considered "after" the top value.
* Limit the analyzed text for highlighting
- Introduce index level settings to control the max number of character
to be analyzed for highlighting
- Throw an error if analysis is required on a larger text
Closes#27517
Previously to this change when DocStats are added together (for example when adding the index size of all primary shards for an index) we naively added the `totalSizeInBytes` together. This worked most of the time but not when the index size on one or multiple shards was reported to be `-1` (no value).
This change improves the logic by considering if the current value or the value to be added is `-1`:
* If the current and new value are both `-1` the value remains at `-1`
* If the current value is `-1` and the new value is not `-1`, current value is changed to be equal to the new value
* If the current value is not `-1` and the new value is `-1` the new value is ignored and the current value is not changed
* If both the current and new values are not `-1` the current value is changed to be equal to the sum of the current and new values.
The change also re-enables the failing rollover YAML test that was failing due to this bug.
