Currently, if you write a date range query with numeric 'to' or 'from' bounds,
they can be interpreted as years if no format is provided. We use
"strict_date_optional_time||epoch_millis" in this case that can interpret inputs
like 1000 as the year 1000 for example.
This PR change this to always interpret and parse numbers with the "epoch_millis"
parser if no other formatter was provided.
Closes#63680
The original description of per-field boosting is incorrect. Boosting a
field does not imply that it is more important relative to other fields.
It simply means that the score is multiplied by the supplied boost
value. Due to the differences in each field's term and document
statistics, it's not possible to imply relative importance of fields
based on the per-field boost value alone.
Added case insensitive support for regex queries.
Forks a copy of Lucene’s RegexpQuery and RegExp from Lucene master.
This can be removed when 8.7 Lucene is released.
Closes#59235
Changes:
* Moves "Notes" sections for the joining queries and percolate query
pages to the parent page
* Adds related redirects for the moved "Notes" pages
* Assigns explicit anchor IDs to other "Notes" headings. This was required for
the redirects to work.
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Elasticsearch 2.0 and installing an oracle JDK, both of which is no
longer valid.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.
Moves the search sort docs from the deprecated 'Request Body Search'
page to a new subpage of 'Run a search'.
No substantive changes were made to the content.
Moves the highlighting docs from the deprecated 'Request Body Search'
chapter to the new subpage of the 'Run a search chapter' section.
No substantive changes were made to the content.
This commit highlights the ability for geo_point fields to be
used in geo_shape queries. It also adds an explicit geo_point
example in the geo_shape query documentation
Closes#56927.
The `lowercase_expand_terms`, `locale` and `all_fields` parameters for
`simple_query_string` have been deprecated and a no-op for at least until 6.0
so we can remove them in 8.0
Warn about potential performance impact when a large number of fields
is used with query string query and no default field.
Re-adds content from #35570.
That content was erroneously removed in #45296.

This commit adds a new point field that is able to index arbitrary pair of values (x/y)
in the cartesian space. It only supports filtering using shape queries at the moment.
Looking into #50237 I realized that two of the examples given in the
documentation around date math rounding for range queries on date fields using
`gt` and `lt` is slightly off by a nanosecond. This PR changes this to the
bounds that are currently parsed using these parameters.
The terms-lookup section of our terms query docs currently state that the
index, id and path fields are optional. They should be marked instead
as required.
Before boost in script_score query was wrongly applied only to the subquery.
This commit makes sure that the boost is applied to the whole score
that comes out of script.
Closes#48465
Add a new cluster setting `search.allow_expensive_queries` which by
default is `true`. If set to `false`, certain queries that have
usually slow performance cannot be executed and an error message
is returned.
- Queries that need to do linear scans to identify matches:
- Script queries
- Queries that have a high up-front cost:
- Fuzzy queries
- Regexp queries
- Prefix queries (without index_prefixes enabled
- Wildcard queries
- Range queries on text and keyword fields
- Joining queries
- HasParent queries
- HasChild queries
- ParentId queries
- Nested queries
- Queries on deprecated 6.x geo shapes (using PrefixTree implementation)
- Queries that may have a high per-document cost:
- Script score queries
- Percolate queries
