WeightFunction#weight to allow dedicated weight calculations per operation. In certain
circumstance it is more efficient / required to ignore certain factors in the weight
calculation to prevent for instance relocations if they are solely triggered by tie-breakers.
In particular the primary balance property should not be taken into account if the delta for
early termination is calculated since otherwise a relocation could be triggered solely by the
fact that two nodes have different amount of primaries allocated to them.
Closes#2984
A first implementation of adding matchers and helper methods to elasticsearch.
The following ones are supported
assertHitCount(searchResponse, 2);
// helper methods to easily access the first hits
assertFirstHit(searchResponse, hasId("foo")):
assertSecondHit(searchResponse, hasType("foo")):
assertThirdHit(searchResponse, hasIndex("foo")):
// methods to access all other hits
assertSearchHit(searchResponse, 5, hasId("10"));
// same as above, but maybe more readable
assertSearchHit(searchResponse.getHits().getAt(5), hasIndex("foo"));
I changed GeoFilterTests to show how it works.
Furthermore I inlined assertHighlight() from HighlighterSearchTests.
The ElasticsearchAssertions class can be used now as a centralized assertion class
in order have a centralized class for every developer to look at.
Custom settings are not always present in the `Settings` that are passed
to `NodeSettingsService.Listener#onRefreshSettings` such that using the defaults
will necessarily override the custom settings if set before.
Closes#2973
Fixed testX and testSingleNodeNoFlush by specifying mapping on index creation instead of using dynamic mapping. Dynamic mapping is updated on the cluster level asynchronously and if mapping changes are not applied to the cluster state before node is closed, these changes are not be available after node restart. While data added in the test is preserved, due to absence of mapping, the test still fails. This is a known issue that we are not planning to fix at the moment.
Currently realtime GET does not take source includes/excludes into account.
This patch adds support for the source field mapper includes/excludes
when getting an entry from the transaction log. Even though it introduces
a slight performance penalty, it now adheres to the defined configuration
instead of returning all source data when a realtime get is done.
The filter method of XContentMapValues actually filtered out nested
arrays/lists completely due to a bug in the filter method, which threw
away all data inside of such an array.
Closes#2944
This bug was a follow up problem, because of the filtering of nested arrays
in case source exclusion was configured.
Analysing a numeric field will return UTF-16 representations of
of Lucenes numeric prefix terms. Those terms are meaningless in general
unless used for lookups in the lucene index. Passing a numeric field
to the analysis action is most likely a bug.
Closes#2953#2952
use the latest Lucene version as specified in o.e.common.lucene.Lucene
and must be upgraded with each lucene release.
This commit adds an assert that fails once the actual lucene version
that is used is higher than the current releases version.
Lucene ships with a version constant that is mainly used to provide consistent behaviour across lucene release versions. Lucene's Analysis capabilities are commonly applied at index and search time such that the search-time behaviour should be identical to the index-time behaviour in most of the cases. Currently ElasticSearch always uses the latest version from Lucene which can break backwards compatibility with the index for users that rely on behaviour that changed in new Lucene version.
Users should always use the version the index was created with unless it's explicitly configured.
closes#2945
don't produce broken positions anymore and prevent certain highlighter bugs that fail with
StringArrayOutOfBoundsExceptions as in #2931
This commit breaks backwards compatibility in terms of highlighting when NGramTokenFilter is used.
The highlighter will highlight the entire terms as produced by the tokenizer instead of the individual
sub-gram. To do sub-gram highlighting, the ngram tokenizer should be used. This behavior was based on
broken NGramTokenFilter behavior which will be fixed in Lucene 4.4 but was ported in this commit
to elasticsearch 0.90. The broken behavior can still be used if a version < LUCENE_42 is used
in the token filter mapping.
Closes#2931
- rename to open_contexts from open, we might have other open stats in the future related to search (lucene index searchers?)
- add a test to verify it works
to the lucene version is that `discreteMultiValueHighlighting` does default to `true`. Yet
we set this anyway in the HighlightingPhase such that the classes are obsolet.
if a single highlight phrase or term was greater than the fragCharSize producing negative string offsets
The fixed BaseFragListBuilder was added as XSimpleFragListBuilder which triggers an assert once Elasticsearch
upgrades to Lucene 4.3
In order to handle exceptions correctly, when classes are not found, one
needs to handle ClassNotFoundException as well as NoClassDefFoundError
in order to be sure to have caught every possible case. We did not cater
for the latter in ImmutableSettings yet.
This fix is just executing the same logic for both exceptions instead of
simply bubbling up NoClassDefFoundError.
When specifying minimum_should_match in a multi_match query it was being applied
to the outer bool query instead of to each of the inner field-specific bool queries.
Closes#2918
If cluster settings are update the REST API returns the accepted values. For
example, updating the `cluster.routing.allocation.disable_allocation` via
cluster settings:
```curl -XPUT http://localhost:9200/_cluster/settings -d '{
"transient":{
"cluster.routing.allocation.disable_allocation":"true"
}
}'```
will respond:
```{
"persistent":{},
"transient":{
"cluster.routing.allocation.disable_allocation":"true"
}
}```
Closes#2907
