Odd warning during search

We are seeing this warning message:

not using index-search for attribute 'Referenceable.qualifiedName'; might
cause poor performance

I have not been able to find a configuration related to indexing/search or
documentation that could help us resolve this.

Can someone help clarify what would cause this?

Thanks!

These are the (known) special characters that would trigger such warnings.

private static boolean isIndexQuerySpecialChar(char c) {
        switch (c) {
            case '+':
            case '-':
            case '&':
            case '|':
            case '!':
            case '(':
            case ')':
            case '{':
            case '}':
            case '[':
            case ']':
            case '^':
            case '"':
            case '~':
            case '*':
            case '?':
            case ':':
            case '/':
            case '#':
            case '$':
            case '%':
            case '@':
            case '=':
                return true;
        }

        return false;
    }

What is the qualified name that you're searching on ? If it has special characters then the index query won't be executed because the indexing backend tokenizes the search string on every occurrence of a special character. 
Hence the warning.

I don't have it of hand, but this is the code snippet with the Atlas client
we used:


      SearchParameters.FilterCriteria qualifiedNameCriteria = new
SearchParameters.FilterCriteria();
      qualifiedNameCriteria.setAttributeName(QUALIFIED_NAME);
      qualifiedNameCriteria.setOperator(SearchParameters.Operator.EQ);
      qualifiedNameCriteria.setAttributeValue(qualifiedName);
      SearchParameters searchParams = new SearchParameters();
      searchParams.setTypeName(typeName);
      searchParams.setExcludeDeletedEntities(true);
      searchParams.setEntityFilters(qualifiedNameCriteria);
      searchParams.setLimit(ATLAS_SEARCH_LIMIT);

      AtlasSearchResult searchResult = atlas.facetedSearch(searchParams);

What is the search criteria that you're working with ? If it's basically search , can you share the request JSON ?
