Read the Docs uses /server-side-search to power our search. This guide explains how to add a “search as you type” feature to your documentation, and how to use advanced query syntax to get more accurate results.
You can find information on the search architecture and how we index documents in our Search docs.

Search query syntax¶
Read the Docs uses the Simple Query String feature from Elasticsearch. This means that as the search query becomes more complex, the results yielded become more specific.
Exact phrase search¶
If a query is wrapped in
" (double quotes),
then only those results where the phrase is exactly matched will be returned.
Exact phrase search with slop value¶
~N (tilde N) after a phrase signifies slop amount.
It can be used to match words that are near one another.
* (asterisk) at the end of any term signifies a prefix query.
It returns the results containing the words with specific prefix.
~N after a word signifies edit distance (fuzziness).
This type of query is helpful when the exact spelling of the keyword is unknown.
It returns results that contain terms similar to the search term as measured by a Levenshtein edit distance.
Build complex queries¶
The search query syntaxes described in the previous sections can be used with one another to build complex queries.
