I have country codes in an index and there are country codes like AT, BE, NO which are also in the English Stop words. For this reason, my search for these countries are not working. I need to have this query working (Search records with AT mentioned in any of the files - AT=Austria) POST myindexes/\_search { "query": { "match": { "\_all": "AT" } } } By default, this is not returning any results. So I turned towards analyzers. In the below settings, I have 3 analyzers with three different type of filters. Despite the three options, its not working. Note, I have added 3 different analyzers for testing purpose only. The mappings and settings are given below . Also sample records created are also given below PUT myindexes { "settings": { "analysis": { "analyzer": { "myanalyzerwithstop":{ "tokenizer" : "standard", "filter" : ["standard", "lowercase", "stop"] }, "myanalyzernostop":{ "tokenizer" : "standard", "filter" : ["standard", "lowercase"] }, "myanalyzerstopwithkeep":{ "tokenizer" : "standard", "filter" : ["standard", "lowercase","mywords"] } }, "filter": { "mywords" : { "type" : "keep", "keep\_words" : ["AT", "NO", "BE","GB"] } } } }, "mappings": { "myindex":{ "\_all" : { "enabled" : true, "analyzer": "myanalyzerstopwithkeep" ``` }, "properties": { "countrywithstop" : { "type": "string", "index": "analyzed", "analyzer": "myanalyzerwithstop" }, "countrywithnostop" : { "type": "string", "index": "analyzed", "analyzer": "myanalyzernostop" }, "countrywithkeep" : { "type": "string", "index": "analyzed", "analyzer": "myanalyzerstopwithkeep" } } } ``` } } The object creation script - PUT myindexes/myindex/1 { "countrywithstop" :"AT", "countrywithnostop" :"AT", "countrywithkeep" :"AT" } PUT myindexes/myindex/2 { "countrywithstop" :"GB", "countrywithnostop" :"GB", "countrywithkeep" :"GB" } PUT myindexes/myindex/3 { "countrywithstop" :"NO", "countrywithnostop" :"NO", "countrywithkeep" :"NO" } -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Bijuv, If you are still searching on the \_all field, try to remove "lowercase" from the keep analyzer: ``` "myanalyzerstopwithkeep":{ "tokenizer" : "standard", "filter" : ["standard", "mywords"] } ``` What's happening is the lowercase filter makes "AT" into "at" and therefore your mywords filter will not have any effect since "at" is not the same as "AT". Or you can set the \_all analyzer to "myanalyzernostop" and it will work correctly also. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi Binh If the filter has only "filter" : ["standard", "mywords"], then by default AT or at will appear in the search result as the STOP filter is removed What Im trying to achieve is : Remove all the default english stop words (use STOP filter) Retain the words that I mention under keep words . For e.g. if I mention AT or BE in the keep filter, it should remove all stop words except AT and BE. How is this achieved.
