Subject [jira] [Commented] (SOLR-11244) Query DSL for Solr
Date Thu, 31 Aug 2017 13:50:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-11244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16148998#comment-16148998
] 

Yonik Seeley commented on SOLR-11244:
-------------------------------------

According to the v2 API spec doc attached to that issue, the JSON Request API should already
be hooked in?
But no, we shouldn't be removing any old query or update APIs, unless they are non-primary
perhaps (i.e. not used by the majority of users).

> It will be great if Solr has a powerful query DSL. This ticket is an extension of [http://yonik.com/solr-json-request-api/].
> Here are several examples of Query DSL
> {code}
> curl -XGET http://localhost:8983/solr/query -d '
> {
>     "query" : {
>         "lucene" : {
>             "df" : "content",
>             "query" : "solr lucene"
>         }
>     }
> }
> {code}
> the above example can be rewritten as (because lucene is the default qparser)
> {code}
> curl -XGET http://localhost:8983/solr/query -d '
> {
>     "query" : "content:(solr lucene)"
> }
> {code}
> more complex example:
> {code}
> curl -XGET http://localhost:8983/solr/query -d '
> { 
>     "query" : {
>         "boost" : {
>             "query" : {
>                 "lucene" : {
>                     "q.op" : "AND",
>                     "df" : "cat_s",
>                     "query" : "A"
>                 }
>             }
>             "b" : "log(popularity)"
>         }
>     }
> }
> {code}
> I call it Json Query Object (JQO) and It defined as :
> - It can be a valid query string for Lucene query parser, for example : "title:solr"
> - It can be a valid local parameters string, for example : "{!dismax qf=myfield}solr
rocks"
> - It can be a json object with structure like this 
> {code}
> {
>   "query-parser-name" : {
>      "param1" : "value1",
>      "param2" : "value2",
>      "query" : <JQO>,
>      "another-param" : <JQO>
>   }
> }
> {code}
> Therefore the above dismax query can be rewritten as ( be noticed that the query argument
in local parameters, is put as value of {{query}} field )
> {code}
> {
>   "dismax" : {
>      "qf" : "myfield"
>      "query" : "solr rocks"
>   }
> }
> {code}
> I will attach an HTML, contain more examples of Query DSL.
