Lucene query to Solr query
Hi,
I have following query which works fine as a lucene query:
+(topics:132)^0.02607211 (topics:146)^0.008187325
-asset_id:doc:en:index.html
But, it does not work if I use it as a solr query with lucene as defType.
For it to work, I need to convert it like following:
q=+((topics:132)^0.02607211 (topics:146)^0.008187325
+(-(asset_id:doc\:en\:index.html))&defType=edismax&q.op=OR
Why does it not work as is? AFAIK syntax given in the first query is
supported by edismax.

Is this odd use-case where one needs to convert Lucene query to Solr query?
Isn't this normal use-case when somebody is trying to port their Lucene
code to Solr?
I mean, is it like a XY problem where I should not even run into this
problem in the first place?

There's nothing like this now. Presumably one might visit queries and
generate Query DSL json, but it might be a challenging problem.

I think this question here in this thread is similar to my question.
https://lucene.472066.n3.nabble.com/Lucene-Query-to-Solr-query-td493751.html
As suggested in that thread, I do not want to use toString method for
Lucene query to pass it to the q param in SolrQuery.
I am looking for a function that accepts org.apache.lucene.search.Query and
returns org.apache.solr.client.solrj.SolrQuery. Is that possible?

edismas is quite different from straight Lucene.
Try attaching &debug=query to the input and
you’ll see the difference.
