Solr 4.1 Helper is a free Chrome extension developed by daniel.blanc. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

This extension aims to provide a convenient solution for users working with the Solr administration page. It allows users to save and restore Solr 4.1 server requests, eliminating the need to repeatedly fill in the same form fields when debugging a design.

By clicking the "Save current query" button, users can persist the query fields in the browser storage. These saved queries are then displayed in a list, and users can easily restore the query fields in the form by clicking on the query name. If a query is no longer needed, it can be removed from the storage by clicking on the cross button next to the query name.

Additionally, the extension offers an "Export" button that copies a JSON representation of the persisted query list to the clipboard. Users can also import a previously exported query list using the "Import" button, providing a seamless way to transfer query data between different instances of Solr 4.1 Helper.
