Search statistics provide an **HTTP API** for tracking searches and collecting statistical data about them. The aggregated statistics expose functionality you can use to enhance the search: autocomplete, spelling suggestions, and related queries.
## Track method
To gather search statistics for later analysis, use the `
Track()` method in the search query:
After adding some autocomplete text in the Search & Navigation user interface under [Manage > Optimization > Autocomplete](🔗), the autocomplete feature can be enabled on the search textbox in the front-end. Add a jQuery script to add autocomplete, as shown below.
The autocomplete example is dependent upon jQuery and jQuery UI scripts used on your website. However, there are no jQuery requirements for Optimizely Search & Navigation Autocomplete. You can use any library of choice or solution to make this work on your website.
Security restrictions may prevent you from using JSONP with Optimizely Search & Navigation’s Autocomplete.
Then, add `
txtSearch` to the search form:
Autocomplete only works from the beginning of a phrase. The search term must begin with the first word. You can get existing autocomplete items from the \_autocomplete/list endpoint: /\_autocomplete/list?q=(%40%20%7C"")YOURWORD.\*
Based on what other users searched for, search statistics can provide spellchecks and popular queries similar to the one passed to the spellchecker. A jQuery example is below.
The spellchecker accepts these parameters:
**query** – (required) the query to return spellchecks for.
**size** – (optional) the number of spellchecks to return.
## Related queries
Sometimes, it is valuable to discover search relationships; for example, people searching for **a** also search for **b**. In search statistics, this is called _related queries_. You can request them with the following jQuery.
Related queries accept these parameters:
**query** – (required) the query to return related queries.
**size** – (optional) the number of related queries to return.
