different interpretation of the same query between solr 7.3.1 and solr 8.4.1

[Danilo Tomasoni <to...@cosbi.eu>]

Hello all,
I noticed that solr8 parses the edismax queries differently from solr7.

the querystring and parsedquery in solr 8.4.1 are

"querystring":"(_query_:\"{!edismax qf='titles subtitles study_brief_title abstracts abstract_background abstract_objective abstract_methods abstract_results abstract_conclusions abstract_other_nasa abstract_other_kie abstract_other_aids abstract_other_aamc abstract_other_publisher abstract_other_pip abstract_other_plain_language_summary keywords medline_chemical_terms medline_mesh_terms' q.op=OR mm=1 v=$subquery1}\" AND (f2:(\"pharmacokinetics\")))",


"parsedquery":"+(DisjunctionMaxQuery(((abstracts_chemical_pubtator_annotation_terms:_query_)^7.0 | (body_nonstandard_species_gnorm_annotation_canonical_terms:_query_)^7.0 | (body_conclusions_species_gnorm_annotation_canonical_terms:_query_)^7.0 | (intervention_model_chemical_tmchemm2_annotation_terms:_query_)^7.0 | ...


that looks like a syntax error ( notice that field:_query_ )

while in solr 7.3.1 the querystring and parsedquery are

"querystring":"(_query_:\"{!edismax qf='titles subtitles study_brief_title abstracts abstract_background abstract_objective abstract_methods abstract_results abstract_conclusions abstract_other_nasa abstract_other_kie abstract_other_aids abstract_other_aamc abstract_other_publisher abstract_other_pip abstract_other_plain_language_summary keywords medline_chemical_terms medline_mesh_terms' q.op=OR mm=1 v=$subquery1}\" AND (f2:(\"pharmacokinetics\")))",


"parsedquery":"+(+(+(DisjunctionMaxQuery((subtitles:rifampicin | abstract_methods:rifampicin | abstract_other_plain_language_summary:rifampicin | abstract_other_pip:rifampicin | keywords:rifampicin | abstracts:rifampicin | abstract_background:rifampicin | medline_chemical_terms:rifampicin | ....

that is correct.

please note also that subquery1 is

"subquery1":"(rifampicin rifampin isoniazid pyrazinamide ethambutol moxifloxacin pretomanid bedaquiline)"


and that df is a very big list of fields.



I attach an example POST request.

I executed the test with curl, this is the command line

(solr 7.3.1)
curl -X POST -H "Content-type: application/x-www-form-urlencoded" --data @request "http://solr2.cosbi.eu/solr/COSBIBioIndex/select?indent=off&wt=json&rows=1&debugQuery=true"

(solr 8.4.1)
curl -X POST -H "Content-type: application/x-www-form-urlencoded" --data @request "http://solr-test.cosbi.eu/solr/COSBIBioIndex/select?indent=off&wt=json&rows=1&debugQuery=true"


Any clue on why this is happening? It seems to me that there should be an obvious change in syntax that I can't find in the documentation and relase notes.
Thank you
