I am experimenting using elasticsearch in a dummy project in django. I am attempting to make a search page using django-elasticsearch-dsl. The user may provide a title, summary and a score to search for. The search should match all the information given by the user, but if the user does not provide any info about something, this should be skipped.
I am running the following code to search for all the values.
client = Elasticsearch()
s = Search().using(client).query("match", title=title_value)\
.query("match", summary=summary_value)\
.filter('range', score={'gt': scorefrom_value, 'lte': scoreto_value})
When I have a value for all the fields then the search works correctly, but if for example I do not provide a value for the summary_value, although I am expecting the search to continue searching for the rest of the values, the result is that it comes up with nothing as a result.
Is there some value that the fields should have by default in case the user does not provide a value? Or how should I approach this?
UPDATE 1 I tried using the following, but it returns every time no matter the input i am giving the same results.
s = Search(using=client)
if title:
s.query("match", title=title)
if summary:
s.query("match", summary=summary)
response = s.execute()
UPDATE 2
I can print using the to_dict().
if it is like the following then s is empty
s = Search(using=client)
s.query("match", title=title)
if it is like this
s = Search(using=client).query("match", title=title)
then it works properly but still if i add s.query("match", summary=summary) it does nothing.
You need to assign back into s:
if title:
s = s.query("match", title=title)
if summary:
s = s.query("match", summary=summary)
