Python : Wildcard Query In Elasticsearch

I want to query a field using wildcard in Elasticsearch but the problem is that the search string is stored in a variable and not available statically. The intended query is : body

Solution 1:

You have to use + concatenation in python.

And you need to escape double quotes. There are many ways to do this. I prefer escaping double quotes as \"

searchWord ="Vi";
query ="{\"query\": {\"wildcard\": {\"Name\": { \"value\" : \""+ searchWord +"?????\" }}}}";
print (query);

searchWord is something that you receive from the user. I hardcoded it.

query is the one you need to form. This is how I formed it \"" + searchWord + "?????\"

Please check and provide any information which I need to consider.

EDIT:

searchWord ="Vi";
x =2;
query ="{\"query\": {\"wildcard\": {\"Name\": { \"value\" : \""+"[a-z]{"+ str(x) +"}"+ searchWord +"?????\" }}}}";
print (query);
