Innovations and new featuresPermanent link for this heading

Global configuration of query and item transformation pluginsPermanent link for this heading

In the new “Global Index Settings“ area, you can now configure transformation plugins that are automatically active for all indices. This does away with the more complex individual configuration.

For more information, see Mindbreeze InSpire configuration .

Profiles on the clientPermanent link for this heading

Profiles now allow you to change the language for individual users and to define the number of search results to be loaded per page.

For more information about the configuration, see Profile configuration.

Improved relevancePermanent link for this heading

The order of the search results now clearly reflects their relevance to the search query. In the new update, the order of search results is automatically altered so that the first hits better match the search query. Extended settings in the relevance model can be configured extensively in the Management Center.

More information at Mindbreeze Query Expression Transformation

Updates in Management CenterPermanent link for this heading

In the future, new Mindbreeze InSpire updates can be installed using the new update wizard. The new SFX file is uploaded without the command line, and the update is executed on a new Mindbreeze InSpire version.

For more information see: Mindbreeze-InSpire-SFX-Update

Exporting search results in Excel and JSON file formatsPermanent link for this heading

In addition to the CSV file format, search results can now also be downloaded in Excel (xlsx), JSON, and ZIP file formats.

For configuration details, see Configuration---Export functionality

PDF preview: new featuresPermanent link for this heading

Navigation between search resultsPermanent link for this heading

In addition to color highlighting the search query, navigation buttons now enable you to navigate to the next hit in the PDF preview.

New interaction possibilities with hyperlinks in PDFsPermanent link for this heading

An API extension allows developers to react to hyperlinks in the PDF preview. For example, an interactive tooltip for a component in a technical drawing can be displayed.

For more information, see Development of search applications

New "suggestlist" component in the search app designerPermanent link for this heading

The new “suggestlist“ component lists the suggestions from the suggest API. For example, “popular searches“ can be displayed under the results list.

For more information, see Development of search applications

New connectorsPermanent link for this heading

SharePoint Online connectorPermanent link for this heading

With this new connector, the content from SharePoint Online can now be indexed. For more information, see SharePoint Online connector configuration.

Google Drive connectorPermanent link for this heading

Mindbreeze InSpire can now index all stored files and Google Docs documents from Google Drive. For more information, see Google-Drive-Connector configuration.

IBM Connections connectorPermanent link for this heading

The new IBM Connections connector allows all content from IBM's on-premises solutions to be indexed. See IBM Connections connector configuration for more information.

GitHub connectorPermanent link for this heading

With the new GitHub connector, content from public and private GitHub repositories can be indexed. See GitHub connector configuration for more information.

Atlassian Jira connectorPermanent link for this heading

Mindbreeze InSpire now supports indexing content from Atlassian Jira. For more information, visit Configuration – Jira Connector.

GSA feed adapter: GSA content feedsPermanent link for this heading

The GSA adapter now supports Google GSA content feeds. More information at GSA adapter service configuration.

Technical upgradesPermanent link for this heading

Web Connector: support for googleon/googleoff tagsPermanent link for this heading

Explanation: Google GSA defines a mechanism for marking certain parts within a single HTML website (e.g. menu, footer) as “non-searchable“. Consequently, these designated sections are not indexed, although the rest of the page is. The marks take the form of HTML comments that are set in pairs.

Example: fish <!--googleoff: index-->shark <!--googleon: index-->dog
“fish“ and “dog“ are indexed, “shark“ is not.

The Mindbreeze InSpire Web Connector now detects googleon/googleoff tags and automatically skips unwanted sections without the need for complicated configuration using XPath rules.

For more information, see Web Connector configuration .

Faster restart of servicesPermanent link for this heading

The system for starting and stopping services has been improved. Indexes are now shut down simultaneously. This reduces the waiting time for configuration changes, especially in large installations. In addition, only the affected services will be restarted if the configuration is changed.

For more information, see Service Restart Behavior after Configuration Changes.

Easier Kerberos configuration with keytab assistantPermanent link for this heading

The new keytab assistant in Management Center simplifies the setup of Kerberos. The assistant automatically detects the Kerberos configuration, diagnoses possible errors, and ensures that the configuration is correct. In the event of an error, the system outputs a detailed error message.

For more information see: Configuration-Kerberos-Authentication

Various optimizationsPermanent link for this heading

Performance optimizationsPermanent link for this heading

  • The index has been optimized and now requires less memory. In addition, performance optimizations mean that the index is also faster now.
  • The configuration surface now loads much faster in large installations.

New version of app.telemetryPermanent link for this heading

Mindbreeze InSpire now has the new app.telemetry version 17.1. release notes.

In rare cases, the updated version is not installed automatically. In this case, please request an updated app.telemetry license.

Additional ChangesPermanent link for this heading

Spectre and MeltdownPermanent link for this heading

Spectre and Meltdown refer to 3 vulnerabilities (Variant 1 – 3) that allow an unprivileged attacker to bypass conventional memory security restrictions in order to gain read access to privileged memory that would otherwise be inaccessible. Mindbreeze strongly advises to install the fixes for InSpire as soon as they are available. Please note that as of this writing the firmware updates are not yet released by Dell and therefore are not available to be updated according to [1].  The fixes have a negative performance impact. As all updates are not yet available we can only measure parts of the impact, which is considered low. Mindbreeze InSpire is interacting with unprivileged third party code remotely via HTTPS, therefore the immediate risk of gaining access to privileged memory is considered impractical [2].

As of today Redhat has already released operating system patches included in the currently released InSpire Update Image. This addresses variant 1, and variant 3. Variant 2 requires firmware update. As soon as the firmware is made available, we will make the update available to our customers.
