Elastic Query String Query Search

Question

I am trying to get records using Query String Query .
My search script is as follows:
I need to search for: "I Love my " AND (HTC OR Iphone OR Samsung)
And I expect a result like:

• I love my HTC
• I love my iphone.
• I love my Samsung.

I just tried a few combinations but didn't work

 { "query": { "query_string": { "default_field": "SearchContent", "query": "\"I Love my\" AND (HTC OR Iphone OR Samsung)" } } } 

How can I do this with a Query String? Or is there another option, I'm stuck. Help me.

Answer 1

The request depends on your _mapping. If you did not define it, then probably a standard analyzer is used. If so, then the tokens:

• I love my HTC → "i", "love", "my", "htc"
• I love my Iphone → "i", "love", "my", "iphone"
• I love my Samsung → "i", "love", "my", "samsung".

Note that markers are lowercase.

The correct query string format is:

 GET /yourindex/_search { "query": { "query_string": { "default_field": "SearchContent", "query": "\"i love my\" AND (samsung OR htc OR iphone)" } } }

Well yes. You can create filtered quesry based on match_all query with filters that interest you, combine and / or filter. Here you want to return documents containing one of three phrases. I guess you don’t want “I like my cake and I have an iphone” to return.

So, something like this (I don’t know if this is enough, tough).

 { "filtered" : { "query" : { "match_all" : {} }, "filter" : { "or" : { "filters" : [{ "fquery" : { "query" : { "query_string" : { "query" : "\"I love my iphone\"", "default_field" : "searchContent", "default_operator" : "and" } } } },{ "fquery" : { "query" : { "query_string" : { "query" : "\"I love my htc\"", "default_field" : "searchContent", "default_operator" : "and" } } } }, { "fquery" : { "query" : { "query_string" : { "query" : "\"I love my samsung\"", "default_field" : "searchContent", "default_operator" : "and" } } } } ] } } } 

}

Answer 3

Try it...

 { "query": { "query_string": { "default_field": "SearchContent", "query": "I Love my *" } } } 

A wild card does not scale well if the data is too large. But it can help if performance is not a major issue (less data).

Answer 4

You can use the query string below to search for the same.

 { "query_string" : { "fields" : ["content", "my_field"], "query" : "\"I love my \" HTC Iphone Samsung" } }
