search glossary term :

query ($input: SearchInput!) {
  search(input: $input) {
    total
    count
    searchResults {
      entity {
        ... on GlossaryTerm {
          urn
          hierarchicalName
          glossaryTermInfo {
            name
            description
            termSource
          }
        }
      }
    }
  }
}

Search vars i am using

search_vars = {"input": {"type": "GLOSSARY_TERM", "query": "*", "count": 50,"filters":filters}}

value for filters i am using :

{
    "field": "glossaryTerm",
    "value": "urn:li:glossaryTerm:Discoverd.PII",
                }

I need to basically filter glossary terms based on Node name, for example, i need all the glossary terms that are not starting with keyword ‘Discovered’

if you're looking for all glossary terms where the name does not have the word "Discovered" in the name I believe you can use the below query:

query getSearchResultsForMultiple {
    searchAcrossEntities(input: { count: 100, types: [GLOSSARY_TERM], query:  "* NOT name: *Discovered*" }) {
    start  
    count
    total
    	searchResults{
          entity {
            urn
            ... on GlossaryTerm {
              properties {
                  name
              }
            }
          }
        }
    }
}
