Faceted Search

In faceted search (also known as out-of-the-box search), information can be accessed based upon dynamic classification. Faceted search uses a faceted classification system in which indexed information can be accessed and explored from various dimensions using filters. The facets allow you to filter data through multiple paths and different ordering, and also click on any combination of facets to get the desired results.

Features and Facets

SearchBlox can perform a customized search using this faceted search functionality. The default facets available are collections, keywords, file type and date. You can filter the search results by selecting the required combination of facets.

How to Perform a Faceted Search

The SearchBlox faceted search can be accessed through the following URL:
localhost:8080/searchblox/plugin/index.html

Provide the search term in the search field and press enter. The search results page with the facets will appear in the left-hand menu as shown in the following screenshot:

Facet Filters

The default facets for filters such as file type, keyword and modified date can be found in the left-hand menu. After selecting each filter, the facets will appear selected with x mark to deselect the same. By clicking the x next to the facet, it can be removed from the search results as shown in the following image.

  • File Type lists the file types available in the search results for filtering.
  • Keywords lists the words that are the keywords of the search, other than the search term results.
  • Modified Date has five options ranging from week to year, along with customized date range.
    You can also add collection as a facet by making changes in ../plugin/data/facet.json
  • Collection lists the collections that have the search results for the given search term.
    Similarly, you can also add other meta tags as facets.

Adding a Facet in SearchBlox

SearchBlox also supports Collection, Title, Description, Language, Author and Subject as facets. The last two facets (author and subject) are applicable for only PDF files.
facet.js is the configuration file that provides options that can be configured to provide search results as required. The path for the facet.js file, after placing the plugin folder in SearchBlox, is ../webapps/searchblox/plugin/facet.js. To add a new facet filter, define the field name, display name and the size of the filter values to be shown in facet.js. Facet filters can be string, number or date types. Except for the predefined facets such as keywords, title, description, size or date, if you need to add more custom facets, you can add them in facet.js (example: facet field: "group").

predictResultSizeParameters for predicted search can be specified here
customDateDisplayTextThis is for custom date label change in facet filters
customDateEnableThis is to enable or disable custom date
relatedQueryEnable or disable related query by giving true or false value for this field. By default it would be true
relatedQueryFieldsIf you want related queries in search results then specify the API key within the field. Also you can limit it based on collection by giving specific column number.
"apikey": "BFC82BE93A351C018CB27C32E1138047",
"field": "content",
"operator": "and",
"limit": "5",
"terms": "10",
"type": "phrase",
"col": ""
dataToBeDisplayedThis is specific for collections like csv and database where results have to appear in tabular format. The fields can be specified here.
If "displayAll" is true within this field all the data would be fetched from the results
tuneTune parameter for relevancy of search results. This can be enabled by giving "enable": "true", within this field
defaultTypeif AND is specified then boolean operator AND would be used in searching multiple terms. If none is specified it would be OR search
pluginDomainThe domain of SearchBlox where the plugin has to fetch results

The contents of facet.js are shown here.

  • If you need to a meta field as facet, then the field has to be mapped in mapping.json. For CSV, database, MongoDB and AWS collections, the values need to be mapped in csv.json, jdbc.json, mongodb.json, amazonS3.json respectively here: ../webapps/searchblox/WEB-INF/.
  • If you need to add a facet field for type number or date, the field needs to be updated in ../webapps/searchblox/WEB-INF/mapping.json for web and file collections. For CSV, database, MongoDB and AWS collections, the values need to be mapped in csv.json, jdbc.json, mongodb.json, amazonS3.json respectively here: ../webapps/searchblox/WEB-INF/.
    ref: Custom Fields in Search

Sorting Search Results

In faceted search, users can sort the search results based on date and relevance using the drop-down provided at the top of the search results and for the search box. By default, it would be in descending order.
The ascending or descending order of sorting can also be given using parameters in the URL. The user can also specify a custom field for sorting using facet.js.

AutoSuggest
Autosuggest/Autocomplete is enabled by default in faceted search for past queries. This feature can be disabled from the search settings if required.
AutoSuggest
