Python Wrapper for elasticsearch

Project description

elasticpy
===========

Python wrapper for the elasticsearch indexing utility.

Author: Luke Campbell <luke.s.campbell@gmail.com>

HOWTO
-----

To begin using elasticpy start by importing.
import elasticpy

To interface with the elasticsearch server use the ElasticSearch object.

search = elasticpy.ElasticSearch()

To form a query use the ElasticQuery objects.

query = elasticpy.ElasticQuery().term('users':'luke')
# and then pass it to the search object
search.search_advanced('twitter','feeds',query)
> {u'_shards': {u'failed': 0, u'successful': 5, u'total': 5},
u'hits': {u'hits': [{u'_id': u'1',
u'_index': u'twitter',
u'_score': 0.30685282,
u'_source': {u'content': u'This is an example.', u'user': u'luke'},
u'_type': u'feeds'}],
u'max_score': 0.30685282,
u'total': 1},
u'timed_out': False,
u'took': 3}

USAGE
-----

* Simple Searching, queries ElasticSearch using GET on a url based query.

search_simple(index, type, key, search_term)

* Advanced Searching, queries to ElasticSearch using a GET method and passing a JSON object containing the detailed query parameters, typically assembled by using an ElasticQuery object.

search_advanced(index, type, query)

* Searching an index, the entails searching the entire index and all the types within.

search_index_simple(index, key, search_term)
search_index_advanced(index, query)

* Queries closely match the query types specified by [QueryDSL](http://www.elasticsearch.org/guide/reference/query-dsl/) used in ElasticSearch. They are wrapped in python methods to make them creation of the objects easier to manage than JSON strings.

query = elasticpy.ElasticQuery().query_string(query='any')
query
> {'query_string': {'allow_leading_wildcard': True,
'analyze_wildcard': None,
'auto_generate_phase_queries': False,
'boost': 1.0,
'default_field': '_all',
'default_operator': 'OR',
'enable_position_increments': True,
'fuzzy_min_sim': 0.5,
'fuzzy_prefix_length': 0,
'lowercase_expanded_terms': True,
'phrase_slop': 0,
'query': 'any'}}

* Filters also closely match the [QueryDSL](http://www.elasticsearch.org/guide/reference/query-dsl/) just like query.

filter = elasticpy.ElasticFilter().term('user','luke').range('age',21,26)
filter
> {'range': {'age': {'from': 18,
'include_lower': True,
'include_upper': False,
'to': 25}},
'term': {'user': 'luke'}}
