The “headless” featurea allows you to reiceve the output of ke_search in JSON format.
In the extension manager you can specify the UIDs of the ke_search content elements and the IP addresses which should be allowed to access the headless function.
Use case examples¶
- Render search results with AJAX.
- Create a headless application and use ke_search in the backend.
- This feature needs at least ke_search 3.8.1.
Please install and configure ke_search, the indexers and the plugins as if you would use ke_search in non-headless context (see “Quickstart” in the ke_search documentation).
Please use the extension settings module, open the “Headless” tab in the ke_search_premium settings and specify the UIDs of the ke_search plugins you want to make available for headless response.
Please also specify the IP address(es) from which access to the headless function should be allowed. Although it is possible to use “*” to make the headless function publicly available, it is recommended to limit the access to only the IP address of your application, because the response will include full database rows e. g. from the pages table (in the “orig_row” property) which may disclose information you want to keep private.
You can access the headless function by adding the parameter “tx_kesearch_pi1[headless_ce]” to specify the content element from which you want to receive the JSON response. The other parameters are the same as you would access ke_search in non-headless mode. Please add the “no_cache” parameter.
For the following examples we assume that the content element with the UID 308 is our search box plugin and the UID 309 is our search result plugin.
Default result list¶
Calling the result list plugin without any further parameters will give you the first 10 results (if not configured otherwise in the plugin settings).
Search plugin (including filters)¶
Calling the search box plugin will give you the search configuration including the filters.
Searching for a search phrase¶
You can use the identfiers and values of the filters you get from calling the search box plugin to compile a search request which includes filtering.
Filtering using a dropdown filter:
Filtering using a checkbox (multiselect) filter:
You can use all the parameters ke_search supports in the non-headless mode (like sorting, pagebrowser settings etc.):
