I'm working off the pyes usage example here
I'm indexing test-index with four documents and querying later using different offsets. The start parameter doesn't change the offset for me, I keep getting the same results regardless of its value. Why is this happening?
from pyes import *
conn = ES(["localhost:9200"])
try:
conn.delete_index('test-index')
except:
pass
conn.create_index('test-index')
mapping = {u'name': {'boost': 1.0,
'index': 'analyzed',
'store': 'yes',
'type': u'string',
"term_vector" : "with_positions_offsets"},
u'title': {'boost': 1.0,
'index': 'analyzed',
'store': 'yes',
'type': u'string',
"term_vector" : "with_positions_offsets"},
u'pos': {'store': 'yes',
'type': u'integer'},
u'uuid': {'boost': 1.0,
'index': 'not_analyzed',
'store': 'yes',
'type': u'string'}}
conn.put_mapping("test-type", {'properties':mapping}, ["test-index"])
conn.index({"name":"Joe Tester", "uuid":"11111", "position":1}, "test-index", "test-type", 1)
conn.index({"name":"Bill Baloney", "uuid":"22222", "position":2}, "test-index", "test-type", 2)
conn.index({"name":"Joe Joseph", "uuid":"33333", "position":3}, "test-index", "test-type", 3)
conn.index({"name":"Last Joe", "uuid":"44444", "position":4}, "test-index", "test-type", 4)
conn.refresh(["test-index"])
q = TermQuery("name", "joe")
r0 = conn.search(q, indices = ["test-index"], start=0, size=1)
r1 = conn.search(q, indices = ["test-index"], start=1, size=1)
r2 = conn.search(q, indices = ["test-index"], start=2, size=1)
print('0: {0}'.format(r0['hits']['hits']))
print('1: {0}'.format(r1['hits']['hits']))
print('2: {0}'.format(r2['hits']['hits']))
output:
$ python pagination.py
0: [{u'_score': 0.19178301, u'_type': u'test-type', u'_id': u'4', u'_source': {u'position': 4, u'name': u'Last Joe', u'uuid': u'44444'}, u'_index': u'test-index'}]
1: [{u'_score': 0.19178301, u'_type': u'test-type', u'_id': u'4', u'_source': {u'position': 4, u'name': u'Last Joe', u'uuid': u'44444'}, u'_index': u'test-index'}]
2: [{u'_score': 0.19178301, u'_type': u'test-type', u'_id': u'4', u'_source': {u'position': 4, u'name': u'Last Joe', u'uuid': u'44444'}, u'_index': u'test-index'}]
My pyes version is 0.16.0
The problem was in how the request was sent to ES, although I'm still not clear on why it failed.
Instead of sending the queries directly to ES like I did originally:
r0 = conn.search(q, indexes = ["test-index"], start=0, size=1)
r1 = conn.search(q, indexes = ["test-index"], start=1, size=1)
r2 = conn.search(q, indexes = ["test-index"], start=2, size=1)
I wrapped my queries in a pyes.query.Search object:
r0 = conn.search(Search(q, start=0, size=1), indexes = ["test-index"])
r1 = conn.search(Search(q, start=1, size=1), indexes = ["test-index"])
r2 = conn.search(Search(q, start=2, size=1), indexes = ["test-index"])
That worked, see the output below:
0s: [{u'_score': 0.19178301, u'_type': u'test-type', u'_id': u'4', u'_source': {u'position': 4, u'name': u'Last Joe', u'uuid': u'44444'}, u'_index': u'test-index'}]
1s: [{u'_score': 0.19178301, u'_type': u'test-type', u'_id': u'1', u'_source': {u'position': 1, u'name': u'Joe Tester', u'uuid': u'11111'}, u'_index': u'test-index'}]
2s: [{u'_score': 0.19178301, u'_type': u'test-type', u'_id': u'3', u'_source': {u'position': 3, u'name': u'Joe Joseph', u'uuid': u'33333'}, u'_index': u'test-index'}]
Ensure your using a search type of Query then Fetch.
