Hi Folks We have a bunch of fields for a document. Lets call them "field1",'field2"....., "FIELD1","FIELD2"...... When we search for a particular text we want to see those records first which has that text in "FIELD1"..."FIELDn" before records from "field1", "field2" etc. Now the complications : a) We have lots of field. Doing internal testing we found that if we copy the fields to a common field(using "copy\_to" something akin to \_all field) and do search only that field then the search is much faster then doing a multi match query on list of fields. Not found any document on this, but this seem to be the case in all our internal testing. b) We have our own analyzer for different copy to field. So lets say I have "my\_own\_analyzed\_all\_field1" on which I am searching. All values from "field1"..... "FIELDn" is copied here. c) The "boost" parameter for field as far I see work for field type( As far as I see its only deprecated for document ). However this only works if the result is going to "\_all' field. It does not seem to be boosting the field getting copied to "my\_own\_analyzed\_all\_field1". So the question is can it be done here? Or do we have to do multi match query with each field boosted by certain factor. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi Folks I have created test data like this in Sense. PUT /myccindexallanalyzed/testobject/\_bulk {"index":{"\_id":1}} {"name":"do not","description":"single test word"} {"index":{"\_id":2}} {"name":"single test word","description":"do not"} I am trying to search for "sin\* test" and want the document which has this phrase in Name field to be first. I do get the document but the one in the description field has higher score. What am I doing wrong here? Here is the query : GET myccindexallanalyzed/testobject/\_search?explain { "query": { "bool": { "should" : [ { "span\_near": {"clauses": [ {"span\_multi":{"match":{"wildcard":{"description":{"wildcard":"sin\*","boost":1.0}}}}} ,{"span\_multi":{"match":{"wildcard":{"description":{"wildcard":"test","boost":1.0}}}}} ] ,"slop":0 ,"in\_order":true,"collect\_payloads":false } }, { "span\_near": {"clauses": [ {"span\_multi":{"match":{"wildcard":{"name":{"wildcard":"sin\*","boost":2.0}}}}} ,{"span\_multi":{"match":{"wildcard":{"name":{"wildcard":"test","boost":2.0}}}}} ] ,"slop":0 ,"in\_order":true,"collect\_payloads":false } } ] ,"minimum\_should\_match" : 1 } } } On Tuesday, September 9, 2014 10:50:21 AM UTC-7, Amish Asthana wrote: > Hi Folks > We have a bunch of fields for a document. > Lets call them "field1",'field2"....., "FIELD1","FIELD2"...... > > When we search for a particular text we want to see those records first > which has that text in "FIELD1"..."FIELDn" before records from "field1", > "field2" etc. > > Now the complications : > a) We have lots of field.

Not seen any reply. Can anyone guide us. Let me ask in another way : a) Lets say i have document with 10 fields. Assume that there is no boosting etc. required for any field. Now lets say we have "\_all" fields encompassing all these fields. Question : Is the query on just "\_all" field faster then field by field query? If so by what factor? ( To me logically it should tokens in "\_all" field should be less than equal to summation of all fields and thus time should be less than field by field, approaching \_all case if all are distinct token.) b) Then the second part of question is how to boost a field; if its getting copied to a copy to field. regards and thanks amish On Tuesday, September 9, 2014 10:50:21 AM UTC-7, Amish Asthana wrote: > Hi Folks > We have a bunch of fields for a document. > Lets call them "field1",'field2"....., "FIELD1","FIELD2"...... > > When we search for a particular text we want to see those records first > which has that text in "FIELD1"..."FIELDn" before records from "field1", > "field2" etc. > > Now the complications : > a) We have lots of field.
