## Potential timeouts
|
|
|
|
Some queries are computationally expensive for our search infrastructure to execute. To keep search fast for everyone, we limit how long any individual query can run. In rare situations when a query exceeds the time limit, search returns all matches that were found prior to the timeout and informs you that a timeout occurred.
|
|
|
|
Reaching a timeout does not necessarily mean that search results are incomplete. It just means that the query was discontinued before it searched through all possible data.
|
|
|
|
## Limitations on query length
|
|
|
|
There are some limits to the length of the queries when searching across {% data variables.product.product_name %}:
|
|
|
|
- Queries longer than 256 characters are not supported
|
|
- You can't construct a query using more than five `AND`, `OR`, or `NOT` operators
|
|
|
|
Specific search types, such as code search, might have additional limitations. Check the documentation for these search types for more information. {% ifversion code-search-upgrade %} For more information on code search limitations specifically, see "[AUTOTITLE](/search-github/github-code-search/about-github-code-search#limitations)."{% endif %}
