Is it possible to make OOTB search function works while publish instance is dead?

[Ka_On_Leung]

For OOTB search component, I see that when I make a request to perform a search on the web server. I see in the dispatcher.log it will make request to the CQ publish instance and return the text result.

Is it possible that when it does the search, it will do the search query only on the web server, so that even the CQ publish some how goes down, the search can still perform successfully?

The Search component works on the publish instance. So if the publisher instance goes down - then the search component will not work. Its a script that runs on the server. See the AEM topic for more information: "Creating the Search Component"

http://dev.day.com/docs/en/cq/current/howto/website.html

Hope this helps

Is it possible that to copy all the indexings file from the publish instance to the web server? So that when a user make a search request on the web server, the web server will make the query locally instead of sending the request to the publish instance.

Thanks for your reply

that is not best practice - i would not recommend that nor have i heard of anyone doing that. The Search component searches content in the JCR (remember that all content is located in the JCR). So if the JCR is down - because Publisher is down - what would you Search for. A Search component is just AEM APIs called from a JSP:

<%@ page import="com.day.cq.wcm.foundation.Search,com.day.cq.tagging.TagManager" %>

<%@include file="/libs/foundation/global.jsp" %><%

%><cq:setContentBundle/><%

    Search search = new Search(slingRequest);

    String searchIn = (String) properties.get("searchIn");

    String requestSearchPath = request.getParameter("path");

    if (searchIn != null) {

        /* only allow the "path" request parameter to be used if it

         is within the searchIn path configured */

        if (requestSearchPath != null && requestSearchPath.startsWith(searchIn)) {

            search.setSearchIn(requestSearchPath);

        } else {

            search.setSearchIn(searchIn);

        }

    } else if (requestSearchPath != null) {

        search.setSearchIn(requestSearchPath);

    }

    pageContext.setAttribute("search", search);

    TagManager tm = resourceResolver.adaptTo(TagManager.class);
