This commit fixes several NPEs caused by implicitly performing a get request for a document that exists with its _source disabled and then trying to access the source. Instead of causing an NPE the following queries will throw an exception with a "source disabled" message (similar behavior as if the document does not exist).:
- GeoShape query for pre-indexed shape (throws IllegalArgumentException)
- Percolate query for an existing document (throws IllegalArgumentException)
A Terms query with a lookup will ignore the document if the source does not exist (same as if the document does not exist).
GET and HEAD requests for the document _source will return a 404 if the source is disabled (even if the document exists).
If we don't care about scoring then for certain candidate matches we can be certain, that if they are a candidate match,
then they will always match. So verifying these queries with the MemoryIndex can be skipped.
This commit moves template support out of the Search API to its own dedicated Search Template API in the lang-mustache module. It provides a new SearchTemplateAction that can be used to render templates before it gets delegated to the usual Search API. The current REST endpoint are identical, but the Render Search Template endpoint now uses the same Search Template API with a new "simulate" option. When this option is enabled, the Search Template API only renders template and returns immediatly, without executing the search.
Closes#17906
`stored_fields` parameter will no longer try to retrieve fields from the _source but will only return stored fields.
`fields` will throw an exception if the user uses it.
Add `docvalue_fields` as an adjunct to `fielddata_fields` which is deprecated. `docvalue_fields` will try to load the value from the docvalue and fallback to fielddata cache if docvalues are not enabled on that field.
Closes#18943
This changes adds a MapperPlugin interface which allows pull style
retrieval of mappers and metadata mappers added by plugins. For now, I
have kept the MapperRegistry, but this should be removed in the future
as it is just a silly container for 2 maps which could themselves be
passed around.
Makes ScriptModule just a plain class that manages building the
ScriptSettings and ScriptService from plugins. When we *need*
to bind ScriptService with guice we bind it in a lambda.
- fix it so that processors with the `ignore_failure` option do not
record their exception in the response
- add more tests to make empty `on_failure`. This now throws an
exception
This makes this sequence:
```
curl -XDELETE localhost:9200/source,dest?pretty
for i in $( seq 1 100 ); do
curl -XPOST localhost:9200/source/test -d'{"test": "test"}'; echo
done
curl localhost:9200/_refresh?pretty
curl -XPOST 'localhost:9200/_reindex?pretty&wait_for_completion=false' -d'{
"source": {
"index": "source"
},
"dest": {
"index": "dest"
}
}'
curl 'localhost:9200/_tasks/Jsyd6d9wSRW-O-NiiKbPcQ:237?wait_for_completion&pretty'
```
Return task *AND* the response to the user.
This also renames "result" to "response" in the persisted task info
to line it up with how we name the objects in Elasticsearch.
This reverts commit 969e953645a4b1a28aaa834ca0c4826ba5ea19a2.
Docs are failing because of the removed functionality. I will
fix the docs before pushing it again.
