We purchased a long time ago the Lucene.net™ Full Text Search plugin from Nopdynamics but this company is impossible to reach and now we are looking to upgrade our current nop version 3.90 to nop 4.30 but could not find any similar plugin.
This Lucene plugin comes as a full package, so we just had to install the plugin and the search is really improved.
The available plugins always require to add a Soir link or connect with an additional partner what we don't like to do.
Is there any company that created something similar like our current Lucene plugin (link: https://www.nopdynamics.com/lucenenet-full-text-search-setup-instructions/)
Please dm me and we can discuss further.
