README

The built-in SilverStripe search form is a very simple search engine. This plugin takes SQL-based searching to the next level, without requiring the implementation of a full-blown search engine like Solr or Elastic Search. It is designed to bring data-oriented filters on top of the simple text search functionality.

Requirements

• SilverStripe 4

Usage

• Create a SearchPage instance (typically at the root of your website). This page only is used to display results, so please refrain from creating multiple instances.
• Configure your website's _config/config.yml (or add _config/search.yml) to define search parameters.
• Run dev/build to instansiate your new configuration (this will also automatically create an instance of SearchPage if one does not exist).
• To overwrite the default SearchPage tmeplate, add a template file to your application: templates/PlasticStudio/Search/Layout/SearchPage.ss

Upgrading from jaedb/search

Ensure you review the search config and update it to match the example config in this repo. Key changes:

1. Table: 'SiteTree_Live' -> Table: 'Page_Live'
2. Add JoinTables: ['SiteTree_Live']

Elemental

• Elemental search is included
• On page or Element save, all content from all Elements is saved to a field called ElementalSearchContent on sitetree.
• Simply include 'SiteTree_Live.ElementalSearchContent' to the list of page columns
• Currently there is no way to exclude individual elements from being included.
• Run IndexPageContentForSearchTask to index element content

Configuration

• types: associative list of types to search
  • Label: front-end field label
  • Table: the object's primary table (note _Live suffix for versioned objects)
  • ClassName: full ClassName
  • ClassNameShort: namespaced ClassName
  • Filters: a list of filters to apply pre-search (maps to DataList->Filter(key => value))
  • Columns: columns to search for query string matches (format Table.Column)
• filters: associative list of filter options
  • Structure: defines the filter's relational structure (must be one of db, has_one or many_many)
  • Label: front-end field label
  • Table: relational subject's table
  • Column: column to filter on
  • Operator: SQL filter operator (ie >, <, =)
  • JoinTables: associative list of relationship mappings (use the key from the types array)
    • Table: relational join table
    • Column: column to join by
• sorts: associative list of sort options. These are used to popoulate a "Sort by" dropdown field in the Advanced Search Form. Sort order of search results will default to the top item in this list.
  • Label: front-end field label
  • Sort: SQL sort string
• search_form_placeholder_text: Change search input field placeholder text (defaults to "Keywords")
• submit_button_text: Text to use on search form submit button (defaults to "Search")

TODO: defaults: Default attributes or settings, as opposed to those submitted through the search form.

Indexing Dataobjects

The search checks canView permissions for Dataobjects before indexing, so you likely need to add:

    public function canView($member = null)
    {
        return true;
    }
