First, check out this 7.2 article on search queries and filters--you'll see that the way to build your queries has changed. It should sitll be valid for 7.4

How does that code behave?
How do you expect it to behave?
Did the API change dramatically or is there a single line that doesn't compile?

In general, you might want to look at the "Breaking Changes" documentation for the intermediate and target versions and identify if they tell you what has changed, why it did, and what to do.

Hi ,

I wanted to know how to upgrade he below code snippet of Liferay 7.1 to Liferay 7.4.Please suggest.

public final void serveResource(ResourceRequest request, ResourceResponse response) throws IOException {
        
        ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY); 
        String keywords = ParamUtil.getString(request, "keywords");
        SearchContext searchContext = new SearchContext();
        searchContext.setCompanyId(themeDisplay.getCompanyId());
        searchContext.setEntryClassNames(new String[] {User.class.getName()});
        
        BooleanQuery fullQuery = BooleanQueryFactoryUtil.create(searchContext);
        
        BooleanQuery searchQuery = BooleanQueryFactoryUtil.create(searchContext);
        searchQuery.addRequiredTerm(Field.ENTRY_CLASS_NAME, User.class.getName());
        
        // Setting up filters.
        fullQuery.add(searchQuery, BooleanClauseOccur.MUST);
        
        //Search for users with Role Mentor
        BooleanQuery userRoleIdQry = BooleanQueryFactoryUtil.create(searchContext);
        Role role = RoleLocalServiceUtil.getRole(themeDisplay.getCompanyId() ,"UIS_ROLE");
        userRoleIdQry.addRequiredTerm("roleIds", role.getRoleId());
        fullQuery.add(userRoleIdQry, BooleanClauseOccur.MUST);
                       
         // keyword as username
        BooleanQuery userFullNameQuery = BooleanQueryFactoryUtil.create(searchContext);
        userFullNameQuery.addRequiredTerm(FULL_NAME, keywords, true);
        fullQuery.add(userFullNameQuery, BooleanClauseOccur.MUST);

        
        // Exclude inactive users
        BooleanQuery statusQuery = BooleanQueryFactoryUtil.create(searchContext);
        statusQuery.addExactTerm(Field.STATUS, WorkflowConstants.STATUS_INACTIVE);
        fullQuery.add(statusQuery, BooleanClauseOccur.MUST_NOT);
        
        try {
            LOG.debug("******************************fullQuery*******************************************"+fullQuery);
            Hits hits = SearchEngineUtil.search(searchContext, fullQuery);
            if (Validator.isNull(hits) || hits.getLength() == 0) 
                LOG.debug("No records match search criteria");
            JSONArray results = JSONFactoryUtil.createJSONArray();
            
            for (Document document : hits.getDocs())   {
                Long casePK = Long.parseLong(document.getField(Field.ENTRY_CLASS_PK).getValue());
                JSONObject jsonObj = JSONFactoryUtil.createJSONObject();
                jsonObj.put("id", casePK);
                jsonObj.put(Field.NAME, document.getField(FULL_NAME).getValue());
                results.put(jsonObj);
            }
            response.getWriter().write(results.toString());
          } catch (SearchException e) {
             LOG.error("Error while searching users ", e);
         }        
       }
