Wordpress Cache-Enabler Plugin Caching search results with standard centminmod install ?

julliuz · Jul 16, 2020

Does anyone know if I can enable search query caching with cache enabler ?
Maybe within the cacheenabler wpincludes config file somehow ?
Any other method ? (I know wp rocket does it but I don't want to change to that one if possible)

Thank you!
(queries are made the standard way: /?s="searchterm"

apparently you can modify cache enable code to enable search caching https://wordpress.org/support/topic/cache-searches/

julliuz · Jul 16, 2020

I found out how to change ?s= to /search/*keyword , now cache enabler started making cached files (after removing the cache exception for searches in the php file) of the results but it isn’t showing them still because the initiator is still ?s=* and thats a query so the query gets processed instead of the /search/page served. Any help would be much appreciated. Maybe nginx can be forced to serve search results that are already in the cache folder somehow ?

I believe you need to modify wordpress code itself.

Also your cache enabler include file at /usr/local/nginx/conf/wpincludes/cache-enabler.domain.com/wpcacheenabler_cache-enabler.domain.com.conf where domain of wordpress site = cache-enabler.domain.com is generated by centmin.sh menu option 22 in your nginx vhost has a general general to ignore/bypass cache for all query strings
Code (Text):
    if ($query_string != "") {
        set $cache_uri 'nullcache';
    }
but that might not be where you issues lie as wordpress code itself needs modifying or if you can find a wordpress plugin that converts ?s= to /search/

julliuz · Jul 16, 2020

?s= is already converted by this function:

function wpb_change_search_url() {
if ( is_search() && ! empty( $_GET['s'] ) ) {
wp_redirect( home_url( "/search/" ) . urlencode( get_query_var( 's' ) ) );
exit();
}
}
add_action( 'template_redirect', 'wpb_change_search_url' );

that's why cache enabler started caching the pages people land on but the initial searches aren't being served as /search/ in chrome dev tools you can see that it still gets initiated by ?s and then people go to /search/ thus the cached version doesn't get served.

eva2000 · Jul 16, 2020

cache enabler include file at /usr/local/nginx/conf/wpincludes/cache-enabler.domain.com/wpcacheenabler_cache-enabler.domain.com.conf where domain of wordpress site = cache-enabler.domain.com is generated by centmin.sh menu option 22 in your nginx vhost contains the $cache_enabler_uri variable used to determine if a request url is in cache or not
Code (Text):
    # default html file
    set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';

    # webp html file
    if ($http_accept ~* "image/webp") {
        set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index-webp.html';
    }
and centmin.sh menu option 22 generated nginx vhost has try_files match which looks to see if the is a cache entry to serve and it looks first in $cache_enabler_uri variable
Code (Text):
  # for wp cache enabler plugin
  try_files $cache_enabler_uri $uri $uri/ $custom_subdir/index.php?$args; 
so if i visited wordpress index page + searched for terms world and wordpress cache, cache enabler with modification to remove is_search cache exclusion would populate with cache items as follows
Code (Text):
ls -lahR /home/nginx/domains/cache-enabler.domain.com/public/wp-content/cache/cache-enabler/cache-enabler.domain.com/

you see the the $cache_enabler_uri varaible defined parameters aren't able to match for /home/nginx/domains/cache-enabler.domain.com/public/wp-content/cache/cache-enabler/cache-enabler.domain.com/search/world/index.html or gzip version

I added Check-Uri header to ?s= query arguments to display and check what $cache_uri nginx sees when you modified wordpress to redirect to /search

Code (Text):

    if ($arg_s) {
      set $cache_uri $request_uri;
      set $check_surl $cache_uri;
    }
    add_header Check-Uri "$check_surl";

    # default html file
    set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';

Code (Text):

curl -IL http://cache-enabler.domain.com/?s=wordpress+cache

Nginx sees $cache_uri as = Check-Uri value of = /?s=wordpress+cache while nginx $cache_uri is look for /search/wordpress+cache to determine if cache entry exists

so won't match in try_files for cache lookup variable $cache_enabler_uri

Code (Text):

  # for wp cache enabler plugin
  try_files $cache_enabler_uri $uri $uri/ $custom_subdir/index.php?$args;

and subsequent /search/wordpress+cache requests won't match in try_files $cache_enabler_uri either

edit: did get a bit further in reassigning $cache_uri with /search/wordpres+cache by changing includes to

Code (Text):

    if ($args ~* s=(.*)) {
      set $cache_uri $request_uri;
      set $check_surl $cache_uri;
      set $cache_uri /search/$1;
    }
    add_header Check-Uri "$check_surl";
    add_header Set-Uri "$cache_uri";

    # default html file
    set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';

So now returned header via Set-Uri is = $cache_uri

Code (Text):

curl -IL http://cache-enabler.domain.com/?s=wordpress+cache

damn I really wish I could stay with cache enabler, guess not.

eva2000 · Jul 17, 2020

If you have Cloudflare in front, just setup page rule to cache everything with edge ttl cache timeout for url path /search/* or something

julliuz · Jul 17, 2020

This might be a weird request but how would you do a nginx rewrite to change:
/?s=*keyword+keyword* to /search/*keyword+keyword* ?

When I browse to domain.com/search/keyword , it serves the cached files also it makes the file when it doesn't exist yet. So I think that by rewriting it from the get go might do the trick ?
Already have this in place to add a trailing slash (otherwise it didn't recognize it, with a trailing slash it does!)
rewrite ^([^.]*[^/])$ $1/ permanent;

eva2000 · Jul 17, 2020

might have worked it out after removing is_search exclusion from cache_enabler.class.php

Code (Text):

diff -u cache_enabler.class.php-orig cache_enabler.class.php-removesearch

             return true;
         }

you would change Wordpress functions.php slightly so redirect has an ending forward slash / - updated, I created a Wordpress Pretty Search Url plugin which can do this functions.php change so you don't need to modify functions.php.

PHP:


function wpb_change_search_url() {
  if ( is_search() && ! empty( $_GET['s'] ) ) {
    wp_redirect( home_url( "/search/" ) . urlencode( get_query_var( 's' ) ) . "/");
    exit();
  }
}
add_action( 'template_redirect', 'wpb_change_search_url' );

then in /usr/local/nginx/conf/wpincludes/cache-enabler.domain.com/wpcacheenabler_cache-enabler.domain.com.conf where domain of wordpress site = cache-enabler.domain.com is generated by centmin.sh menu option 22, reassigning $cache_uri with /search/wordpres+cache by changing parts of includes above the initial set $cache_enabler_uri to

July 20, 2020: made some changes in /usr/local/nginx/conf/wpincludes/cache-enabler.domain.com/wpcacheenabler_cache-enabler.domain.com.conf

from

Code (Text):

   if ($args ~* s=(.*)) {
     set $cache_uri $request_uri;
     set $check_surl $cache_uri;
     set $cache_uri /search/$1;
   }
   add_header Check-Uri "$check_surl";
   add_header Set-Uri "$cache_uri";

   # default html file
   set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';
 
   # webp html file
   if ($http_accept ~* "image/webp") {
       set $cache_enabler_uri_webp '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index-webp.html';
   }

to the below version so Nginx takes over from Wordpress redirects so PHP-FPM request is totally bypassed for query string ?s= requests and specific /search/ location match so that you can do more specific things in future i.e. rate limit within /search/ if needed

Code (Text):

   if ($args ~* s=(.*)) {
     set $cache_uri $request_uri;
     set $check_surl $cache_uri;
     set $cache_uri /search/$1/;
     set $cache_uri_search /search/$1/;
     set $cache_enabler_uri_search '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri_search}index.html';
   }
   location ~ /search/(.*) {
     set $cache_uri $request_uri;
     set $check_surl $cache_uri;
     set $cache_uri_search $request_uri;
     set $cache_enabler_uri_search '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${check_surl}index.html';
     try_files $cache_enabler_uri_search $cache_enabler_uri_webp $cache_enabler_uri $uri $uri/ $custom_subdir/index.php?$args;
   }
   add_header Check-Uri "$check_surl";
   add_header Set-Uri "$cache_uri";

   # default html file
   set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';

   # webp html file
   if ($http_accept ~* "image/webp") {
       set $cache_enabler_uri_webp '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index-webp.html';
   }

   if (-f $document_root$cache_enabler_uri_search) {
     set $search_exists $cache_enabler_uri_search;
     return 302 https://$host$cache_uri_search;
   }
   if (!-f $document_root$cache_enabler_uri_search) {
     set $search_exists $cache_enabler_uri_search;
   }
   #add_header Check-File "$search_exists";

Search Cache Invalidation Cronjob

Centmin Mod 123.09beta01's centmin.sh menu option 22 wordpress auto installer with Cache Enabler caching selected will also generate an optional cronjob to invalidate and remove Cache Enabler cached files from cache and look similar to:

Remove Cache Enabler's cached files every day at 11:16pm (every 24hrs).

Code (Text):

16 23 * * * echo "cache-enabler.domain.com cacheenabler cron"; sleep 174s ; rm -rf /home/nginx/domains/cache-enabler.domain.com/public/wp-content/cache/cache-enabler/* > /dev/null 2>&1

With above /search/ caching modifications, you could setup a separate /search/ cache invalidation cronjob which can have a shorter or longer interval than default Cache Enabler cache time.

For example delete /search/ cached files every 5 minutes

Code (Text):

*/5 * * * * echo "cache-enabler.domain.com cacheenabler search cron"; sleep 14s ; rm -rf /home/nginx/domains/cache-enabler.domain.com/public/wp-content/cache/cache-enabler/search/* > /dev/null 2>&1

Yeah interesting problem to solve for. Might want to write a wordpress plugin for the functions.php changes so you don't need to edit functions.php directly.

@jcat and @rdan might like this too

I use this one: https://wordpress.org/plugins/code-snippets/

Code Snippets is an easy, clean and simple way to run PHP code snippets on your site. It removes the need to add custom snippets to your theme’s functions.php file.

I made a quick Pretty Search Url plugin just for the functions.php part centminmod/pretty-search-url

Is it just my idea or does that php function only rename/redirect after the call to the database as it still has to call to php to actually rename the thing? Would a nginx rewrite maybe be better ? before it ever hit anything and when it sees the full url it just serves that one ?

maybe I'm completely off haha

with cache enabler cached search

Hmm interesting, I installed this setup a year ago or so. Did anything ever change in the config files since then ? Is there a place where I can see a freshly setup'd cache enabler option 22 configs by any chance ?

easiest way is on a test server or local virtualbox centmin mod, run centmin.sh menu option 22 to create a test wordpress cache enabler site and then inspect and copy over the latest configs to your live instance
