I have tried a dozen different ways to query the patent_abstract parameter with multiple words, but have been unable to. Similar results occur when hitting the patent_title parameter (basically anything with full text doesn't work for me).
This produces results:
https://api.patentsview.org/patents/query?q={"_and":[{"_text_all":{"patent_abstract":"Marvel"}}]}
And this produces results:
https://api.patentsview.org/patents/query?q={"_and":[{"_text_all":{"patent_abstract":"Tesla"}}]}
But these do not:
https://api.patentsview.org/patents/query?q={"_and":[{"_text_all":{"patent_abstract":"Marvel"}},{"_text_all":{"patent_abstract":"Tesla"}}]}
https://api.patentsview.org/patents/query?q={"_and":[{"_text_any":{"patent_abstract":"Marvel Tesla"}}]}
I am also trying to get it so I can query the patent abstract with both include and exclude words/phrases, but similarly, no results are occurring.
How do I query multiple words from the abstract and how would I exclude a word from abstract in conjunction with the include?
Having issues getting complex queries to work with text parameters
