How do I check whether an index exists or not using a python query?
I'm passing my index as a variable assigned outside the query as :-
i=int(datetime.datetime.now().strftime('%d'))+1
indextring="index"
for m in range (i-10,i):
d = datetime.datetime(2016, 10, m, 18, 00).strftime('%Y-%m-%d')
index1=datestring+d
subfix="_"+datetime.datetime(2016, 10, m, 18, 00).strftime('%Y-%m-%d')
es=Elasticsearch(['localhost:9200'])
res = **es.search(index='{0}'.format(index1)**, doc_type="log",size=10000, from_=0, body={ "query": {
"match": {
....Match condition follows
}
}
}})
Now, some of the index are not present for a particular date, however I want the process to run irrespective of that. I'm getting the following error when the index is not present-->
elasticsearch.exceptions.NotFoundError: TransportError(404, u'index_not_found_exception')
I'm not sure how the exception handling works in elasticsearch.
