Add option to cache results

Hi, I have added code to cache the results stored in table.

mytungsten → made their first commit to this issue’s fork.

As is, the code

    $cache_key = 'search_results:' . md5(serialize($results));
    if ($cache = $this->cacheManager->get($cache_key)) {
      return $cache->data;
    }

caches the full results set as part of the key, meaning the entire search process needs to run prior to fetching this cached data.

The cache check/retrieval/set should likely surround the call to search_fields in searchButton and be keyed to the search parameters in order to bypass the full search process if cached data is present.

Additionally, we'll need to at least have a configurable option to cache or not, and ideally, options to set number of cached entries and/or cache duration. These latter can be incremental improvements, but there needs to be the option to disable caching at the least.

Hi @cskeers,

I have done the required changes please review and provide feedback to let me know if we need to improve the approach.

Please find the changes/implementation below -

• Added an option to enable/disable caching from settings form.
• Added an option to set cache duration (in seconds), visible only when cache enable checkbox is checked.
• Added a new checkbox field in the Search Form "Invalidate cache", if checked it will invalidate search results cache first and perform new search. Visible only if caching is enabled.

Attaching screenshots for reference -

This is now on the 1.x develop release for folks to start reviewing.

Hello @mytungsten @manish-31
I have reviewed the MR and it is working as expected.
When enabling invalidate cache it is taking more time in comparison to when disable it.
