Autosuggestion

The built-in autosuggestion function provides a user-friendly way to find products, categories, content or downloads which match the given search criteria.

When you type in main search field, different and configurable search results appear.

Autosuggestion has four different independent modules: product, category, content and download.

Configuration

Tip

The order of module configuration keys represents the order of display in the suggestion box.

Overriding autosuggestion services

There are four autosuggestion services:

SearchBundle/Service/SearchAutosuggestAllService.php
SearchBundle/Service/SearchAutosuggestCategoryService.php
SearchBundle/Service/SearchAutosuggestContentService.php
SearchBundle/Service/SearchAutosuggestDownloadService.php

Search logic is built in the searchProducts() method. Output is generated in getDisplayText() and generateHtml(). Template is rendered in generateHtml().

All autosuggestion services implement the SearchAutosuggestInterface interface. Their service definitions are, for example:

search_service_id: siso_search.autosuggest_service.product

To create a new autosuggestion service, you need to implement the interface and define the service ID in autosuggestion configuration.

Autosuggestion templates

Each autosuggestion section has its own template located in EshopBundle/Resources/views/Search/autosuggest.

All templates have access to the resultLine array, which has all information returned by Solr. You can use this information to adapt the template without overriding the services.

Product template

The search_autosuggest_product_line.html.twig template renders:

• image (if it set)
• autosuggestion text (usually "SKU - Product Name")
• add to basket button.

The add to basket button must have the js-add-to-basket class. This allows Ajax to perform adding the product to basket.

The object link is generated as a link, and is not using the link functionality of the autosuggestion JS module. The link goes to the autosuggesttion redirect controller, which redirects according to the type parameter.

search_autosuggest_product_line.html.twig

Category template

The search_autosuggest_category_line.html.twig template only displays an icon for category and autosuggest text.

Content template

The search_autosuggest_content_line.html.twig template only displays an icon for content and autosuggest text.

Download template

The search_autosuggest_download_line.html.twig template only displays an icon for download and autosuggest text. The download link is generated in the autosuggest redirect controller.

set_bold_text Twig function

The set_bold_text Twig function marks user search terms in autosuggest search result as <strong>.

For example, if user searches for "DMX", then all "DMX" occurrences have the <strong> tag.

Note

Autosuggestions need to be generated as quickly as possible, so do not add additional logic with heavy processing in the template or anywhere else.

For example, avoid using image transformation functions. If you need an image of a given size or features, it is strongly recommended to transform it at indexing time using an indexer plugin and then use the processed image.

Autosuggestion filters

Autosuggestion filters are applied automatically to avoid displaying elements that may be hidden or restricted to certain users.
