Modular structure

The Intrexx search system is modular in a multi-tiered manner to guarantee the greatest level of flexibility.

Search plugins

Search plugins help you to search through the various entities used in the portal such as application data or files. It's possible to add plugins that are tailored to your individual needs. A set of five standard plugins is already available, these cover the most common requirements. These plugins are for:

Search modules for Connectors

Searching through application data uses the search plugin for application data. This is usually sufficient for systems connected using a Connector because SQL-based data storage systems can be indexed and searched through using it. By default, these are: In cases where it isn't possible or desired to perform a global indexing (e.g. because a login with all of the permissions isn't available), the search modules for the Connectors can be employed. These make used of the external system's own search functions. Currently, modules are available for the following external sources:

Search engine adapter

Intrexx uses an external search engine for searching and indexing. The adapter for Apache Solr is provided with the delivered package and is installed when using the standard configuration. The Solr Adapter supports the Intrexx portal server, external individual instances and the SolrCloud installation.

Solr search server

The Apache Solr server runs as an individual process. If a single process isn't enough, Apache Solr can also be run as a Cloud installation. Indexing FileWalker directories uses the Solr server, the portal server isn't involved here. Apache Solr can be configured in many ways. Intrexx defines logical default settings when setting up the server but doesn't overwrite modifications so that almost no limits are set for implementing your individual requirements.

Functional features

Search results format with view pages

Search results can be processed as needed using view pages in addition to button configurations.


The following criteria affect the ranking of search results: The user can choose between using the settings determined by the administrator or to use his own.


The search results can be sorted independently from the ranking, if for example the hit quality doesn't have the first priority when being displayed. The following sortings are available: Here as well, the user can choose between using the settings determined by the administrator or to use his own.

Filtering / Faceted search

The search result can be filtered according to the users' requirements by using the desired applications or facets. Facets (e.g. Industries) can be defined by the administrator and assigned to individual data fields. When searching, the user is shown the facets that can be used for the context and can then filter the information precisely (e.g. Industry = IT industry). To support the user in this, the available values are presented as buttons.


The search module is multilingual. The application's developer can determine the languages in which the data is indexed and searched through. The different language indexes can contain various fields. Users select in which language they'd like to search. Depending on the language chose, different search result lists will be displayed.

Suggestion lists

When entering search terms, suggestions that relate to what's been entered will be shown. With Intrexx's default settings, this list contains terms from the data being searched through. Dictionary sources, e.g. specialist terms databases, are also available. These can be integrated by making a corresponding modification to the Solr configuration.


If a search term is sent with potentially incorrect spelling, an option will be displayed on the answer page as well as the found results. This option offers the user to select the correct term and then to search by this term. Alternatively, the system can automatically search for the correct term straight away, based on a rule.

Search term statistics

The search can anonymously keep track of the search terms in a file. In the Portal Manager, an area is available with a selection of interpretation options, e.g. most popular search terms and trending searches. The protocol file contains JSON data so that individual, browser-based interpretations can be implemented easily.
