This product information (PI) defines the scope of usage and the features of Mindbreeze InSpire services. In addition, it provides an overview of the application interfaces and supported platforms.
Mindbreeze InSpire is a software system enabling the search for information objects in a corporate context ("Enterprise Search Software"). Information objects can be any kind of information contained in structured, partially structured or unstructured storage systems. For most use cases these information objects will be document files in a file system, e-mails in an e-mail box system or documents in a document management system or archive.
Mindbreeze InSpire comprises a multi-stage service-oriented architecture for indexing and searching document files and e-mails on desktop and server computers in enterprises.
For accessing systems containing contents to be indexed (for search) – i.e. data sources – the following architecture components are utilized: index service, filter service, crawler service, query service and client service. The chart below shows the logical components of this architecture.
The above chart shows the system for indexing typical schematic data sources. The components correspond to the essential working steps of the indexing process and will be discussed in the following chapters.
All components communicate based on HTTP/S connections.
The crawler searches the source system exhaustively for new and changed contents that need to be indexed.
This can be achieved in two ways:
The Mindbreeze InSpire – Filter Service enables extraction and filtering of the textual information from various file types. For this purpose, document files are forwarded by Mindbreeze InSpire - Crawler Service to Mindbreeze InSpire - Filter Service.
Note: As of many proprietary formats the filter service cannot guarantee that the text/HTML output is 100% identical to the original file content.
In this working step, the actual index for full text search is created or updated if the source system was changed. The index store can be considered as storage with index information which optimized to answer search queries.
Mindbreeze InSpire – Index Services store objects/documents with each up to 200 metadata and a maximum of 10MB per metadata value. The maximum document size is 1GB including metadata.
The clients connect with Mindbreeze InSpire – Query Service to query the index. Query loads can be distributed by utilizing several Mindbreeze InSpire – Query Service and Client Service services. Several types of clients can be used (e.g. Mindbreeze InApp client, to be integrated into third-party products), which can be realised based on Mindbreeze InSpire SDK.
The Mindbreeze InSpire – Web Client connects with the Client Service to send queries to the Query Service.
Mindbreeze InSpire – Management Service enables central configuration and deployment of services for Mindbreeze Enterprise Search.
Mindbreeze InSpire – Advanced Configuration helps you to configure a distributed Mindbreeze InSpire infrastructure.
An essential component for securing access rights is the so-called access check. The access check ensures that the context of the user logged onto the system is evaluated for any potential search result and applied so that only those search results a user has the appropriate rights for will be displayed. This can be an external authorization of results or the authorization of results against an ACL (access control list) stored in the index. This depends on the data source connected via a specific connector.
The context of files and documents that are displayed as search results in a client (within the context of a query) is provided by this component. This enables, for example, the provision of application-specific context menu entries for data and documents in the search result list.
This section shows all features of Mindbreeze InSpire.
Mindbreeze InSpire comprises the following SDK interfaces:
The Mindbreeze InSpire SDK was updated. Please make sure you use the updated SDK for future development.
Mindbreeze InSpire 20.5 Version supports the following SDK versions:
Mindbreeze InSpire provides a central configuration tool for creation, regular maintenance and administration of index catalogues. In addition, this central tool distributes the system components to the servers of the entire system. Central administration comprises all components of Mindbreeze InSpire (Mindbreeze InSpire – Crawler Service, - Filter Service, - Index Service, - Query Service, - Client Service) from a single point.
For viewing and editing files on the local appliance a web-based File Manager interface is provided in the Management Service.
Editing and viewing is only supported for text files encoded in UTF-8. Files larger than 10MB can be opened read-only. For details on the supported formats for syntax highlighting please refer to the documentation of the used component version 5.51.0.
Binary files cannot be edited or viewed but downloaded instead.
Server-side contents are indexed by Mindbreeze InSpire – Crawler Service component at regular intervals. The intervals can be defined for each data source (in seconds).
Re-indexing is in general not necessary for a software update from version 2016 Spring Release to the current Mindbreeze InSpire product version.
Indexes created with a current version cannot be opened by older versions.
Existing indexes are downward compatible without further configuration changes unless explicitly noted.
Mindbreeze InSpire 20.5 supports the data sources listed below for indexing, navigation and interaction during search. Additional data sources can be integrated via the Mindbreeze InSpire Connector Interface and Mindbreeze InSpire Software Development Kit (SDK) made available.
LDAP / Microsoft Active Directory
Microsoft SharePoint 2007, Microsoft SharePoint 2013/2016/2019 and Microsoft SharePoint Online
Mindbreeze InSpire – Web Connector allows to crawl intranet and extranet sources by following links extracted from HTML sources. The following policy can be restricted to different levels: all, site only, link-depth, sitemap. Access restrictions for the Web Connector are set to unrestricted public access, meaning, if you need to restrict access to certain web content you need to implement a plugin based on the Mindbreeze InSpire – Connector Framework (SDK) that fits your situation and need.

Mindbreeze InSpire supports the Unicode standard (UTF-8 and UTF-16) – in this way, all language and character set systems defined by this standard are supported.
The queries Mindbreeze InSpire Web Client sets off against server-side contents are taken over by Mindbreeze InSpire - Client Service of Mindbreeze InSpire architecture.
Users can search in one or more index catalogues at the same time using Mindbreeze InSpire Web Client. The catalogues can be located on one or more servers. The search results originating from specific indexes can be displayed or hidden as required by the user.
Mindbreeze InSpire enables an exact search for words (word based search) and for groups of words (phrase search). Such search will only display those results which contain the entire search term (single word or phrase).
Mindbreeze InSpire has an intuitive query language as known from Internet search engines.
By default, all search terms separated by space characters are forwarded to the search engine via a logic AND operator. A search for phrases can be performed by using quotation marks. The results can be limited by specifying the file type (file extension) and by specifying a category (e-mail, file, etc.) (see user manual).
In addition to the automatic AND operation, the Boolean operators "AND" and "OR" and brackets can be used. This enables performing a more detailed search.
Proximity of words can be used by "NEAR" to display preferably those results where both search terms are closer together.
The search also supports wildcards at the ending of words. The search functionality automatically provides a wildcard search in a special situation. During a search in the "title" metadata, wildcards are implicitly supported at the beginning and at the end of the search term; e.g.; a search for "report" will return results for *report* in the "title" metadata.
The search results are displayed in the main window according to categories. Depending on the search result, the following categories may be displayed (if there are results in the respective category):
The number of hits selected by the user are displayed for each category. Besides the navigation buttons ("Next", "Back") the hits of each category are dynamically classified to find the result faster. The type and manner of classification depends on the sorting of the result. If the result is sorted by date, classification will be done in time segments. Depending on the dimension of time covered by all results, results of this category will be divided into years, quarters and months (so-called "drill down" over time).
This section describes how to preview, highlight search terms and how to range and navigate in search results.
The main window displays the search results in two levels of detail. The overview only displays essential elements (e.g. name, place or date) to get a relatively quick overview of the results; such display varies according to the metadata which is available for the hits. In the more detailed view, a text preview of the content is provided, trying to display relevant passages of the summary text saved in the index. Each search term is highlighted in a different colour.
During the search the results are sorted within a category according to semantic relevance or chronologically, displaying the more important or more recent elements first. In the case of a chronological sorting the date of the last modification is used.
Alternatively, a ranking algorithm may be chosen which considers several criteria, including the number of times a search term is contained in a document and in what position (content-based ranking) for calculating a ranking based on the quality of a search result. When searching several phrases, the proximity of the phrases is considered, like when searching with "NEAR".
Mindbreeze InSpire allows for a simple and very quick navigation through the search results by means of the contextual navigation elements. In addition to the buttons for browsing (forward and backward), the divisions calculated online and dynamically are available. This enables a behaviour for fast navigation called "drill-down" in database technology. Even without knowing much about a searched object (few search terms), the result can be found simply and quickly.
In addition to opening a result (starting the associated application), Mindbreeze InSpire provides many possibilities for processing the searched object. Depending on the type, the context menu offers options for opening an object with other programs, opening the containing folder, copying the object to the Microsoft Windows clip board or displaying it in the Microsoft Windows Explorer. For each data source (source system) this menu is adapted to the conditions of the data source via the context interface and/or extended.
Mindbreeze InSpire offers so called „Search Tabs“. “Search Tabs” allow to constraint search requests for certain views. “Search Tabs“ are defined in user profile files and can be
Mindbreeze InSpire displays only those search results for which the current user has access rights (at least read-only access)..
For access checking Mindbreeze InSpire supports the following options according to the data source.
