bq. What about multi-valued parameters
It seems that local params work well in this case. As you can see, dismax
qparser has multiple-value parameters (qf field) and it also tested in the
patch.
{code}
{
query : {
dismax : {
query : 'A NJ'
qf : ['cat_s^100', 'where_s^0.1']
}
},
filter : '-id:2',
fields : id
}
{code}
Another test is bool qparser, Its 'should' field is multi-value which contain
sub-queries.
{code}
{
'query': {
'bool' : {
'should' : [
'id:1',
'id:2'
]
}
}
}
{code}
The above query will be rewritten into {!bool should='id:1' should='id:2'}
bq. Is that really the full patch (16K)?
Yeah, that's the full patch :)

> Query DSL for Solr

> Key: SOLR-11244
> URL: https://issues.apache.org/jira/browse/SOLR-11244
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Cao Manh Dat
> Assignee: Cao Manh Dat
> Attachments: SOLR-11244.patch, SOLR-11244.patch, SOLR-11244.patch,
> Solr Query DSL - examples.html
>
>
> 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.
