Hi Guys, I have two types in a index, one is used for indexing topics and another one is used for indexing comments. Here is the sample mapping: _Topic_: curl -XPUT [http://localhost:9200/bbs/topic/\_mapping](http://localhost:9200/bbs/topic/_mapping) -d' { "topic": { "\_timestamp": { "enabled": true }, "properties": { "title": { "type": "string", "store": true, "term\_vector": "with\_positions\_offsets", "indexAnalyzer": "ik", "searchAnalyzer": "ik", "include\_in\_all": true, _"boost": 8_ }, "content": { "type": "string", "store": true, "term\_vector": "with\_positions\_offsets", "indexAnalyzer": "ik", "searchAnalyzer": "ik", "include\_in\_all": true, _"boost": 4_ } } } _Comment_: curl -XPUT [http://localhost:9200/bbs/comment/\_mapping](http://localhost:9200/bbs/comment/_mapping) -d' { "comment": { "\_timestamp": { "enabled": true }, "properties": { "title": { "type": "string", "store": true, "term\_vector": "with\_positions\_offsets", "indexAnalyzer": "ik", "searchAnalyzer": "ik", "include\_in\_all": true, _"boost": 0_ }, "content": { "type": "string", "store": true, "term\_vector": "with\_positions\_offsets", "indexAnalyzer": "ik", "searchAnalyzer": "ik", "include\_in\_all": true, _"boost": 4_ } } } I want to search theses two types(title,content of Topic and only content of Comment) at the same time, however, I do not want to match the "title" field of comments, since the title is the same with its corresponding topic, matching the title field of a comment does not make any sense. I have tried to set the boost value of Comment's title field to zero but it seems does not work.. I think a simple solution is to set the "title" of Comment with "not\_analyzed", but I also want to highlight the matching words in the title, so it's better to also index the title field but let it have little effects on scoring.. Could someone please give me some hints? Thanks! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

How do you know that the search is not working? Can you post an example query and perhaps an example explanation? If you are searching against the all field, you can set include\_in\_all to false for that field. You are better off not searching a field instead of trying to set a boost.
