I think the other users can have a similar problem, so I decided to fix it quickly. * I added something like [_.debounce from lodash](https://lodash.com/docs/4.17.15#debounce). It should fix your issue. Currently after type “my names is jhon doe and i am american” you have about 38 AJAX requests. After my improvements, you will have max few requests or one if you type this phrase fast enough. * The patch will be added in the next plugin release. If you want to test it, I can send you a package. I have finished it and this feature is on the testing stage. You can contact me by email. * Best Damian Góra * Thread Starter [code222](https://wordpress.org/support/users/code222/) * (@code222) * [6 years, 7 months ago](https://wordpress.org/support/topic/bug-overload-server/#post-11915123) * Thanks for faster solution and reply, if require more 1 week to release the next update i prefer to send me the package now, otherwise i will wait.. * Where i can download the package ? are necessary a request by email to receive the package updated ? * Plugin Author [Damian Góra](https://wordpress.org/support/users/damian-gora/) * (@damian-gora) * [6 years, 7 months ago](https://wordpress.org/support/topic/bug-overload-server/#post-11921245) * I added changes to the development version of the plugin. To download it, go to [https://wordpress.org/plugins/ajax-search-for-woocommerce/advanced/](https://wordpress.org/plugins/ajax-search-for-woocommerce/advanced/) and scroll down to the section “PREVIOUS VERSIONS”. Download “Development version”. * It’s still the beta version, so be careful and make backup if you want to test it on the live website. * Best Damian Góra Viewing 3 replies - 1 through 3 (of 3 total) The topic ‘BUG OVERLOAD SERVER’ is closed to new replies. * ![](https://ps.w.org/ajax-search-for-woocommerce/assets/icon-256x256.png?rev= 2883754) * [FiboSearch - Ajax Search for WooCommerce](https://wordpress.org/plugins/ajax-search-for-woocommerce/) * [Frequently Asked Questions](https://wordpress.org/plugins/ajax-search-for-woocommerce/#faq) * [Support Threads](https://wordpress.org/support/plugin/ajax-search-for-woocommerce/) * [Active Topics](https://wordpress.org/support/plugin/ajax-search-for-woocommerce/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/ajax-search-for-woocommerce/unresolved/) * [Reviews](https://wordpress.org/support/plugin/ajax-search-for-woocommerce/reviews/) ## Tags * [ajax](https://wordpress.org/support/topic-tag/ajax/) * 3 replies * 2 participants * Last reply from: [Damian Góra](https://wordpress.org/support/users/damian-gora/) * Last activity: [6 years, 7 months ago](https://wordpress.org/support/topic/bug-overload-server/#post-11921245) * Status: resolved
