Varun Thacker commented on SOLR-11244:
--------------------------------------
Should we be directly mapping between the old param names here?
For example,
{code}
curl -XGET http://localhost:8983/solr/query -d '
{
"query" : {
"lucene" : {
"df" : "content",
"query" : "solr lucene"
}
}
}
{code}
It is still using {{df}}. Given the JSON structure and the chance to rename
things we could use {{default_field}} ?
Here's another example :
{code}
curl -XGET http://localhost:8983/solr/query -d '
{
query : "*:*",
filter : [
{
"prefix" : {
"f" : "myfield",
"query" : "foo"
}
}
]
}'
{code}
Maybe {[f}} should really be {{field}} ?
The question is more generic : Should we rethink the param names where
necessary or keep the old names ?

> 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.
