Display Settings

The table below details the display settings for a project. The name, variable name, variable type, description, and default are defined for each setting.

Note: Your Watson™ Explorer Engine search application may or may not require the configuration of these parameters. If the description of the parameters listed here does not clearly identify its potential use in your search application, please contact IBM support for clarification.

Table 1. Display Settings
Setting Name	Type	Description
Number of results per page (render.list-show)	number	Maximum number of results initially displayed in the results list. The state parameter (modified when browsing the output) can modify this. Default: 20
Number of clusters displayed (render.tree-show)	number	Maximum number of clusters initially displayed at each level of the tree (with a "More" link to expand the list). Default: 10
List of the maximum number of clusters shown by default per level (render.tree-show-levels)	string	Space separated list of integers, each integer corresponds to the maximum number of clusters shown at a certain level by default. For example, setting it to '10 3' will display a maximum of 10 clusters at the top level and 3 at the second level. A value of -1 specifies no limit. Default: -1
Ratio above which subclusters are shown by default rather than top clusters (render.tree-show-subclusters-ratio)	number	If a subcluster has a score s1 (this score is based on the # of documents and the rank of the documents it contains), it will take priority over a cluster at the level above containing less than s1/render.tree-show-subclusters-ratio within the limits set by render.tree-show-levels. For example, setting this option to 0 will never show any subclusters. Setting it to -1 will show all possible subclusters within the limit of render.tree-show-levels. Default: -1.000000
Maximum number of results shown for each site (render.collapse-show)	number	When set to a value greater than 0, this option turns on "site collapsing" (see collapse-key) and limits the number of results coming from the same site that can be shown in the main search results list. Default: -1
Ratio under which collapsing is disabled (render.collapse-min-ratio)	number	If too many search results are collapsed (which will always be the case when the search performed is a site search), site collapsing is turned off by this option. This is the minimum ratio between the number of results shown in the main list if collapsing is turned on versus off. Default: 0.500000
Document score ratio under which subsquent collapsed results are not shown (render.collapse-min-doc-score-ratio)	number	In a collapsed set, subsequent results are only shown if their score is higher than this ratio times the score of the first result in the set. This is used in order to avoid promoting low score documents too much by collapsing them with high score documents. Default: 0.700000
Insert documents in state tree (render.tree-num-docs)	number	Maximum number of documents inserted into the tree under each node. Default: 0
Max sources level (render.expand-sources-max-level)	int	When offering source selection, hide all levels below this by default (the user will have to toggle them to do sub-selections). Default: 10
Display XSL (render.function)	string	The XSL stylesheet defined in the Display section for rendering the Watson Explorer Engine output from XML to HTML. (This XSL is saved as a function node called by the default parser.) Default: custom-display
Advanced form sources (render.sources)	string	List of sources (or source bundles) offered for selection in the advanced form. Default: example-source-bundle
Input form (render.form)	string	Name of the form (defined in the Syntax > Input Forms section) displayed. This is, in particular, the name of the default form used in the front page and all the result pages. In the default setup this variable can be set by the `form` CGI parameter (see the Main XML) allowing different forms to be displayed on different pages (for example, the advanced form after clicking on the "advanced search" link setting a different `form` parameter). Default: simple
Input form (advanced) (render.advanced-form)	string	Name of the form (defined in the Syntax > Input Forms section) referred to in the advanced search link (and displayed in the advanced search page by setting the `form` parameter, see the input form variable render.form). Default: advanced
Display scores (render.display-scores)	boolean	Display a score (from 0 to 100%) with each result. Default: false
Display language (render.language)	enum	The language used for all text in the end-user display. Default: english
Hide user profile tabs (render.hide-profile-tabs)	separated-enum-set	Toggle hiding of the tabs displayed on a user's profile page Default: none
XSL parser (render.parser)	string	The name of the XSL parser used to convert the XML state into HTML. Note that by default this loads the function defined by render.function and the XSL defined by render.extra-xsl. It is unlikely that you need to change this variable. Default: query-meta
Display XSL for preferences pages (render.preferences-function)	string	The XSL stylesheet defined in the Display section for rendering the preferences pages of the user interface.
Display alerts of project type (render.alert-projects)	enum	Choose which of the user's alerts will be shown. All Alerts: Show alerts created with any project Current Project: Show only alerts that were created in the current project (other): Specify alerts from which projects to display Alerts for the current project and alerts with no project attribute will always be shown regardless of what this variable is set to. Default: unset
Additional XSL code (render.extra-xsl)	string	XSL code which will be added dynamically to the default XSL parser. Convenient to change the layout when reclustering.
Quirks mode (render.quirks-mode)	boolean
