I need to make a query in elasticsearch, such that, in the following text: "I want to go on holiday to New York with my family" find: "New York" in the field of a nested. I in my data I have a field that contains the word "New York" which is the type Nested and not_analyzed. Anyone know how to do this?
The query and I got it, and nobody help me.
Use a phrase query. From the docs:
{ "match_phrase" : { "message" : "this is a test" } } I do think that having "not_analyzed" is going to be a problem for you, as you actually want an analyzed field. You can specify the type of analyzer to use, which may work. But I would recommend using an analyzed field, if possible.
If you are willing to pay the space cost, I would recommend using a multi field with analyzed and not_analyzed parts. here is an example:
"sender": { "type" : "multi_field", "fields" : { "sender" : {"type" : "string", "index" : "analyzed"}, "sender_not_analyzed" : {"type" : "string", "index" : "not_analyzed"} } } 
not_analyzed means what it says, it isn't analyzed. It will be indexed as the literal string passed in, in a single token. If you make it analyzed, it will be tokenized and filtered in such a way as to make it useful for full-text searching. So do that.
Please see the documentation of ElasticSearch Analysis.
not_analyzed to analyzed.not_analyzed is not correct, and should be changed, for this type of search. I imagine you have switched to a WildcardQuery, or something along those lines if you kept with a not_analyzed field, which means it will perform a linear search through the entire index, and performance on large data sets will drop through the floor.
