eDisMax parser issue running over multiple fields

Enviornment ==> solr - solr-8.9.0, java version "11.0.12" 2021-07-20 LTS

Following .csv file is indexed in solr

books_id,cat,name,price,inStock,author,series_t,sequence_i,genre_s
0553573403,book,Game Thrones Clash,7.99,true,George R.R. Martin,"A Song of Ice and Fire",1,fantasy
0553573404,book,Game Thrones,7.99,true,George Martin,"A Song of Ice and Fire",1,fantasy
0553573405,book,Game Thrones,7.99,true,George,"A Song of Ice and Fire",1,fantasy

I want to search for a book with having a name saying 'Game Thrones Clash'(with mm=75%) and author George R.R. Martin(with mm=70%.)

Now I want to search book-name in only the 'name' field having its minimum match value as well. Also, the author needs to be searched in author, with different mm values.

field-type : text_general is configured for fields :'name','author' with multivalued as false.

Query shall run over input field 'name'(mm=75%) having the value 'Game Thrones Clash' and author(mm=70%) having the value 'George R.R. Martin'.

There are 3 criteria over which results will be displayed, Only those results shall be displayed which satisfy all the following three criteria:

1. if there is a minimum of 75% of tokens are fuzzy matches in the 'name' field, then it should result in output.
2. if there is a minimum of 70% of tokens are fuzzy matches in the 'author' field, then it should result in output.
3. if field 'inStock' has value 'true'.

Output shall contain the following result.

0553573403 (name - 75% matched as well author 70% matched)
0553573404 (name - 75% matched as well author 70% matched)

Following books_id will not contain in output.

0553573405 (name - 75% matched but author not 70% matched)

I understand that Extended DisMax includes query parameters 'mm'(Minimum should match) with fuzzy search functionality, but the following query is giving all 3 results.

Can someone help me in writing edismax query or any other way around?

Nested Queries can specify different query parameters for different parts of the query.

+_query_:"{!edismax mm=75% df=name} Game~ Thrones~ Clash~"
+_query_:"{!edismax mm=70% df=author} George~ R.R.~ Martin~"
+inStock:true

• Nested Queries are specified by using _query_: as the prefix (see references [1], [2]).
• Local Params [3] {! ... }... specify the query parser and its parameters by prefixing the query string.
  • query type [4] eDisMax [5]: {!type=edismax}... or just {!edismax}...
  • minimum [should-term] match (mm) [6]: {!mm=75%}...
  • default field (df) [7]: {!df=author}...
• Requiring both of two subqueries can be specified via either of the following:
  • +query1 +query2
  • query1 AND query2
• Line breaks are for clarity, all lines are within one query parameter (q=).
  • (If multiple q= parameters exist, adding a debugQuery=true parameter shows that only one is parsed.)

Testing

Steps to reproduce test with a local Solr 9, in Cloud Mode for the Schema Designer page:

• Command line: solr-9.0.0/bin/solr start -e cloud
• answer questions until return to command prompt
• In web browser, open Solr Admin: http://localhost:8983/solr/
• On the Schema Designer tab,
• click New Schema
• Name New Schema: eDisMaxTest1
• Copy From: _default
• click Add Schema
• Under Sample Documents, past csv data and clicked Analyze Documents.
• Under Schema Editor, select fields author and name and
• changed type to text_general.
• disabled the [ ] Multi-Valued checkbox.
• clicked Update Schema
• To find URL: from Schema Designer page, open browser F12 debugger,
• enable the Network tab,
• perform a query: from the Query Tester, click RunQuery
• copy the path http://localhost:8983/api/schema-designer/query
• copy the parameters _=1658489222229 and configSet=eDisMaxTest1 (values may differ).

Request: one query string
