elastic v0.7.0

NEW FEATURES

• New function scroll_clear() to clear search contexts created when
  using scroll() (#140)
• New function ping() to ping an Elasticsearch server to see if
  it is up (#138)
• connect() gains new parameter es_path to specify a context path,
  e.g., the bar in http://foo.com/bar (#137)

MINOR IMPROVEMENTS

• Change all httr::content() calls to parse to plain text
  and UTF-8 encoding (#118)
• Added note to docs that when using scroll() all scores are
  zero b/c scores are not calculated/tracked (#127)
• connect() no longer pings the ES server when run, but can
  now be done separately with ping() (#139)
• Let http request headers be sent with all requests - set with
  connect() (#129)
• Added transport_schema param to connect() to specify
  http or https (#130)
• By default use UUIDs with bulk API with docs_bulk() (#125)

BUG FIXES

• Fix to fail well on empty body sent by user (#119)
• Fix to docs_bulk() function so that user supplied doc_ids
  are not changed at all now (#123)

elastic v0.6.0

Compatibility for many Elasticsearch versions has improved. We've tested on ES versions
from the current (v2.1.1) back to v1.0.0, and elastic works with all versions.
There are some functions that stop with a message with some ES versions simply
because older versions may not have had particular ES features. Please do let us
know if you have problems with older versions of ES, so we can improve compatibility.

NEW FEATURES

• Added index_settings_update() function to allow updating index settings (#66)
• All errors from the Elasticsearch server are now given back as JSON.
  Error parsing has thus changed in elastic. We now have two levels of error
  behavior: 'simple' and 'complete'. These can be set in connect() with the
  errors parameter. Simple errors give back often just that there was an error,
  sometimes a message with explanation is supplied. Complete errors give
  more explanation and even the ES stack trace if supplied in the ES error
  response (#92) (#93)
• New function msearch() to do multi-searches. This works by defining queries
  in a file, much like is done for a file to be used in bulk loading. (#103)
• New function validate() to validate a search. (#105)
• New suite of functions to work with the percolator service: percolate_count(),
  percolate_delete(), percolate_list(), percolate_match(), percolate_register().
  The percolator works by first storing queries into an index and then you define
  documents in order to retrieve these queries. (#106)
• New function field_stats() to find statistical properties of a field without
  executing a search (#107)
• Added a Code of Conduct
• New function cat_nodeattrs()
• New function index_recreate() as a convenience function that detects if an
  index exists, and if so, deletes it first, then creates it again.

MINOR IMPROVEMENTS

• docs_bulk() now supports passing in document ids (to the _id field)
  via the parameter doc_ids for each input data.frame or list & supports using ids
  already in data.frame's or lists (#83)
• cat_*() functions cleaned up. previously, some functions had parameters
  that were essentially silently ignored. Those parameters dropped now
  from the functions. (#96)
• Elasticsearch had for a while 'search exists' functionality (via /_search/exists),
  but have removed that in favor of using regular _search with size=0 and
  terminate_after=1 instead. (#104)
• New parameter lenient in Search() and Search_uri to allow format based
  failures to be ignored, or not ignored.
• Better error handling for docs_get() when gthe document isn't found

BUG FIXES

• Fixed problems in docs_bulk() in the use case where users use
  the function in a for loop, for example, and indexing started over,
  replacing documents with the same id (#83)
• Fixed bug in cat_() functions in which they sometimes failed
  when parse=TRUE (#88)
• Fixed bug in docs_bulk() in which user supplied document IDs weren't being
  passed correctly internally (#90)
• Fixed bug in Search() and Search_uri() where multiple indices weren't
  supported, whereas they should have been - supported now (#115)

DEFUNCT

• The following functions are now defunct: mlt(), nodes_shutdown(), index_status(),
  and mapping_delete() (#94) (#98) (#99) (#110)

elastic v0.5.0

NEW FEATURES

• Added index_settings_update() function to allow updating index settings (#66)

MINOR IMPROVEMENTS

• Replace RCurl::curlEscape() with curl::curl_escape() (#81)
• Explicitly import non-base R functions (#80)

BUG FIXES

• Fixed problems introduced with v1 of httr

elastic 0.4.0

NEW FEATURES

• New function Search_uri() where the search is defined entirely in the URL itself.
  Especially useful for cases in which POST requests are forbidden, e.g, on a server
  that prevents POST requests (which the function Search() uses). (#58)
• New function nodes_shutdown() (#23)
• docs_bulk() gains ability to push data into Elasticsearch via the bulk http API
  from data.frame or list objects. Previously, this function only would accept a file
  formatted correctly. In addition, gains new parameters: index - The index name to use.
  type - The type name to use. chunk_size - Size of each chunk. (#60) (#67) (#68)

MINOR IMPROVEMENTS

• cat_*() functions gain new parameters: h to specify what fields to return; help to
  output available columns, and their meanings; bytes to give numbers back machine
  friendly; parse Parse to a data.frame or not
• cat_*() functions can now optionally capture data returned in to a data.frame (#64)
• Search() gains new parameter search_path to set the path that is used for searching.
  The default is _search, but sometimes in your configuration you've setup so that
  you don't need that path, or it's a different path. (023d287)

BUG FIXES

• In docs_mget() added internal checker to make sure user passes in the right combination of
  index, type, and id parameters, or index and type_id, or just index_type_id (#42)
• Made index, type, and id parameters required in the function docs_get() (#43)
• Fixed bug in scroll() to allow long scroll_id's by passing scroll ids in the body instead
  of as query parameter (#44)
• In Search() function, in the error_parser() error parser function, check to see if
  error element returned in response body from Elasticsearch, and if so, parse error, if not,
  pass on body (likely empty) (#45)
• In Search() function, added helper function to check size and from parameter
  values passed in to make sure they are numbers. (#46)
• Across all functions where index and type parameters used, now using RCurl::curlEscape()
  to URL escape. Other parameters passed in are go through httr CRUD methods, and do URL escaping
  for us. (#49)
• Fixed links to development repo in DESCRIPTION file

v0.3.0

This is the first version to go to CRAN - so all notes are included here.

elastic 0.3.0

NEW FEATURES

• Added a function scroll() and a scroll parameter to the Search() function (#36)
• Added the function explain() to easily get at explanation of search results.
• Added a help file added to help explain timem and distance units. See ?units-time and
  ?units=distance
• New help file added to list and explain the various search functions. See ?searchapis
• New function tokenizer_set() to set tokenizers
• connect() run on package load to set default base url of localhost and port of 9200 -
  you can override this by running that fxn yourself, or storing es_base, es_port, etc.
  in your .Rprofile file.

IMPROVEMENTS

• Made CouchDB river plugin functions not exported for now, may bring back later.
• Added vignettes for an intro and for search details and examples (#2)
• es_search() changed to Search().
• More datasets included in the package for bulk data load (#16)
• All examples wrapped in \dontrun instead of \donttest so they don't fail on CRAN checks.
• es_search_body() removed - body based queries using the query DSL moved to the Search()
  function, passed into the body parameter.

elastic 0.2.0

IMPROVEMENTS

• Remoworked package API. Almost all functions have new names. Sorry for this major change
  but it needed to be done. This brings elastic more in line with the official Elasticsearch
  Python client (http://elasticsearch-py.readthedocs.org/en/master/).
• Similar functions are grouped together in the same manual file now to make finder related
  functions easier. For example, all functions that work with indices are on the index manual
  page, and all functions prefixed with index_(). Thematic manual files are: index, cat,
  cluster, alias, cdbriver, connect, documents, mapping, nodes, and search.
• Note that the function es_cat() was changed to cat_() - we avoided cat() because as
  you know there is already a widely used function in base R, see base::cat().
• We changed cat functions to separate functions for each command, instead of passing
  the command in as an argument. For example, cat('aliases') becomes cat_aliases().
• The es_ prefix remains only for es_search(), as we have to avoid conflict with
  base::search().
• Removed assertthat package import, using stopifnot() instead (#14)

elastic 0.1.0

NEW FEATURES

• First version.
