Overview of search functions
Elasticsearch search APIs include the following functions:
Search() - Search using the Query DSL via the body of the request.
Search_uri() - Search using the URI search API only. This may be
needed for servers that block POST requests for security, or maybe you don't need
complicated requests, in which case URI only requests are suffice.
msearch() - Multi Search - execute several search requests defined
in a file passed to
search_shards() - Search shards.
count() - Get counts for various searches.
explain() - Computes a score explanation for a query and a specific
document. This can give useful feedback whether a document matches or didn't match
a specific query.
validate() - Validate a search
field_stats() - Search field statistics
percolate() - Store queries into an index then, via the percolate API,
define documents to retrieve these queries.
More will be added soon.
