'must' function not working in elasticsearch - elasticsearch

Question

I am new to Elasticsearch and working with a database. I would like to do a query like this:
curl -X GET http://localhost:9200/project/flat_order/_search?pretty=true -d'
{ query:{
bool:{
must:{range:{created_at:{gte:"2012-01-01 00:00:00",lte:"2012-02-01 00:00:00"}}}},
{should:[{term:{status:"canceled"}}],minimum_number_should_match:1}
}
}
}'
and I am getting an error.
"error" : "SearchPhaseExecutionException[Failed to execute phase [query], total failure; shardFailures {[YfeNrRnOTOqLOtQt65uPVw][project][1]: SearchParseException[[project][1]: from[-1],size[-1]: Parse Failure [Failed to parse source [ { query:{ bool:{ must:{range:{created_at:{gte:\"2012-01-01 00:00:00\",lte:\"2012-02-01 00:00:00\"}}}}, {should:[{term:{status:\"canceled\"}}],minimum_number_should_match:1} } } }]]]; nested: QueryParsingException[[project] Failed to parse]; nested: JsonParseException[Unexpected character ('{' (code 123)): was expecting either valid name character (for unquoted name) or double-quote (for quoted) to start field name\n at [Source: [B#3742925a; line: 1, column: 102]]; }{[YfeNrRnOTOqLOtQt65uPVw][project][2]: SearchParseException[[project][2]: from[-1],size[-1]: Parse Failure [Failed to parse source [ { query:{ bool:{ must:{range:{created_at:{gte:\"2012-01-01 00:00:00\",lte:\"2012-02-01 00:00:00\"}}}}, {should:[{term:{status:\"canceled\"}}],minimum_number_should_match:1} } } }]]]; nested: QueryParsingException[[project] Failed to parse]; nested: JsonParseException[Unexpected character ('{' (code 123)): was expecting either valid name character (for unquoted name) or double-quote (for quoted) to start field name\n at [Source: [B#3742925a; line: 1, column: 102]]; }]",
"status" : 500
}
What to do?
Thanks in advance.
This is the error I am getting without those braces(enclosing should)

Looking at the error detail, I believe the problem is that you've got an extra level of nesting for your should clause which you shouldn't have. Instead of:
must: { ... },
{ should: { ... },
minimum_number_should_match:1}
}
Try:
must: { ... },
should: { ... },
minimum_number_should_match:1}
EDIT: Your edited code looks like this is your query:
query:{ bool:{ must:{range:{created_at:{gte:\"2012-01-01 00:00:00\",
lte:\"2012-02-01 00:00:00\"}}}}, should:[{term:status:\"canceled\"}}],
minimum_number_should_match:1 }
which, formatted, would be:
query:{
bool:{
must:{
range:{created_at:{gte:\"2012-01-01 00:00:00\",lte:\"2012-02-01 00:00:00\"}}
}
},
should: [
{term:{status:\"canceled\"}}
],
minimum_number_should_match:1
}
... which has the should outside the bool part. In other words, you've got too many closing braces after your must clause. I believe it should be:
query:{
bool:{
must:{
range:{created_at:{gte:\"2012-01-01 00:00:00\",lte:\"2012-02-01 00:00:00\"}}
},
should: [
{term:{status:\"canceled\"}}
],
minimum_number_should_match:1
}
}
