Hi, I want to increase a significancy for some terms in the query. E.g. increase term 'iphone' in phrase 'I like iphone'. The recipe i found so far is 'query\_string': { "query": { "query\_string": { "query": "I like iphone^5.0" } } } The first question is do I lose the 'analysis' for this query. I mean if I set up stemmer will it work? Or for that kind of query the string will be processed 'as is'. And the second - Are there any better ways to do it? Mb I should use boolean query with term boosting instead? Thanks! ps posted to nabble previously, but seems it ignored the post. ---

The query string syntax gets converted into multiple queries combined with bool and dismax queries anyway, so you can use the query DSL to combine queries with different boosts yourself clint ---

Thanks a lot Clinton, I'm starting to understand how it works. Should the query below be a rough equivalent of the previous one? curl -XGET 'localhost:9200/test/item/\_search?pretty=true' -d ' { "query": { "bool": { "should": [ { "text": { "\_all": "I like iphone" } }, { "term": { "\_all": { "value": "iphone", "boost": 5.0 } } } ] } } }' btw are there any tricks to find out what lucene query I get after the ES processing?

Most of the queries map one to one to the Lucene Query. text is a bit different since it analyzes the text and then constructs a boolean / prefix / phrase prefix query out of it.
