Help:WSSearchFront

From Linux Web Expert

The WSSearchFront extension is a front-end for WSSearch written in Vue.js

For installation instructions see the extension page

For full-text search and showing highlighted result snippets WSSemanticParsedText need to be installed and Semantic MediaWiki has to be configured to use elasticStore and store raw text in Elasticsearch with the following setting in LocalSettings.php
$smwgElasticsearchConfig["indexer"]["raw.text"] = true;

Configuration

The WSSearchFront extension must be configured using the WSSearchFrontend parser function

There are 3 types of configuration:

  • Settings, without a prefix
  • Filter settings, prefixed with a @
  • Result settings, prefixed with a ?

Configurations can have setting options prefixed with a #

Example configuration: 

{{#WSSearchFrontend:
|size=10
|title=Page Title
|@Tag
|@Year
    #display=range
    #max=20
    #type=date
    #label=Publication year
|?Users
    #display=link
|?Image
    #display=image
|?Rating
    #display=template
    #template=Rating icon
}}

#template=Icon for search

#template <template> used with #display=template
#label <text> adds a label in front of the displayed property value. When table layout is used it defines the tabel column header name ?Rating#label=Page rating
#highlight true highlights the search term on the displayed property value ?Description#highlight=true

Facets filter settings

Facet filters are defined by adding an @ in front of the property name. All settings are optional. When no display setting is used the default checkboxes are displayed.

Filter properties also need to be set in the WSSearchConfig, except for display type ask combobox, search, datepicker, date and range see WSSearch for more information

Some display types need a setting with an ask query, see Semantic MediaWiki ask query string for more information about them.

Styling and layout

WSSearchFront can be styled using CSS. Components are logically named using BEM convention, and the layout is defined with CSS Grid. You can just add your own style-sheet, by adding your CSS to common.css or you could use TemplateStyles.

Layout

Below you find the default layout, grid-template-columns defines the columns sizes, grid-template-rows define the row sizes.

The different components can be moved around by changing the grid-template-areas. In the default layout the search component spans over the whole first row. 

.wssearch {
  display: grid;
  grid-template-columns: 20ch 1fr auto;
  grid-template-rows:
    auto
    minmax(2em, auto)
    auto
    1fr;
  grid-template-areas:
    "search search search"
    "selected selected order"
    "filters total total"
    "filters main main";
  grid-gap: 0.5em 2em;
}

The available components are:

  • search this is the search input including the search button
  • selected this is the area where the pills for selected filter show up
  • order this is the area where the sort options drop-down will show if sort options are set in the configuration
  • filters this is where the different facet filters will be located
  • total this where the result count will show up
  • main this is the area where the search result are shown, including the pagers

Variables

WSSearchFront uses CSS variables to define colors and icons, the following variables are available to override

  • --base-color
  • --base-color-lighter
  • --base-color-darker
  • --tint-1
  • --border-1
  • --star-size

Icons

  • --search-icon
  • --clear-icon
  • --check-icon
  • --next-icon
  • --back-icon
  • --down-icon
  • --up-icon

Development

WSSearchFront is written with Vue.js and is pre-built. For performance and for old wiki support reasons. The development repository is based on Vue-CLI and includes mock data and development modules for easy development.

It can be found here WSSearch development repository.

The final build files are added to the module folder in the WSSearchFront extension folder.
