Adding\n * wildcards will increase the number of documents that will be found but can also have a negative\n * impact on query performance, especially with wildcards at the beginning of a term.\n *\n * Terms can be restricted to specific fields, e.g. `title:hello`, only documents with the term\n * hello in the title field will match this query. Using a field not present in the index will lead\n * to an error being thrown.\n *\n * Modifiers can also be added to terms, lunr supports edit distance and boost modifiers on terms. A term\n * boost will make documents matching that term score higher, e.g. `foo^5`. Edit distance is also supported\n * to provide fuzzy matching, e.g. 'hello~2' will match documents with hello with an edit distance of 2.\n * Avoid large values for edit distance to improve query performance.\n *\n * Each term also supports a presence modifier. By default a term's presence in document is optional, however\n * this can be changed to either required or prohibited. For a term's presence to be required in a document the\n * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and\n * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not\n * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.\n *\n * To escape special characters the backslash character '\\' can be used, this allows searches to include\n * characters that would normally be considered modifiers, e.g. `foo\\~2` will search for a term \"foo~2\" instead\n * of attempting to apply a boost of 2 to the search term \"foo\".\n *\n * @typedef {string} lunr.Index~QueryString\n * @example

+/**
+ * Although lunr provides the ability to create queries using lunr.Query, it also provides a simple
+ * query language which itself is parsed into an instance of lunr.Query.
+ *
+ * For programmatically building queries it is advised to directly use lunr.Query, the query language
+ * is best used for human entered text rather than program generated text.
+ *
+ * At its simplest queries can just be a single term, e.g. `hello`, multiple terms are also supported
+ * and will be combined with OR, e.g `hello world` will match documents that contain either 'hello'
+ * or 'world', though those that contain both will rank higher in the results.
+ *
+ * Wildcards can be included in terms to match one or more unspecified characters, these wildcards can
+ * be inserted anywhere within the term, and more than one wildcard can exist in a single term. Adding
+ * wildcards will increase the number of documents that will be found but can also have a negative
+ * impact on query performance, especially with wildcards at the beginning of a term.
+ *
+ * Terms can be restricted to specific fields, e.g. `title:hello`, only documents with the term
+ * hello in the title field will match this query. Using a field not present in the index will lead
+ * to an error being thrown.
+ *
+ * Modifiers can also be added to terms, lunr supports edit distance and boost modifiers on terms. A term
+ * boost will make documents matching that term score higher, e.g. `foo^5`. Edit distance is also supported
+ * to provide fuzzy matching, e.g. 'hello~2' will match documents with hello with an edit distance of 2.
+ * Avoid large values for edit distance to improve query performance.
+ *
+ * Each term also supports a presence modifier. By default a term's presence in document is optional, however
+ * this can be changed to either required or prohibited. For a term's presence to be required in a document the
+ * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and
+ * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not
+ * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.
+ *
+ * To escape special characters the backslash character '\' can be used, this allows searches to include
+ * characters that would normally be considered modifiers, e.g. `foo\~2` will search for a term "foo~2" instead
+ * of attempting to apply a boost of 2 to the search term "foo".
+ *
+ * @typedef {string} lunr.Index~QueryString
+ * @example
Simple single term query
+ * hello
+ * @example
Multiple term query
+ * hello world
+ * @example
term scoped to a field
+ * title:hello
+ * @example
term with a boost of 10
+ * hello^10
+ * @example
term with an edit distance of 2
+ * hello~2
+ * @example
terms with presence modifiers

+description: Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.
+group: components
+aliases:
+ - "/components/"
+ - "/docs/4.6/components/"
+toc: true
+---
+
+## Examples
+
+Alerts are available for any length of text, as well as an optional dismiss button. For proper styling, use one of the eight **required** contextual classes (e.g., `.alert-success`). For inline dismissal, use the [alerts jQuery plugin](#dismissing).
+
+{{< example >}}
+{{< alerts.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+
+ A simple {{ .name }} alert—check it out!
+
{{- end -}}
+{{< /alerts.inline >}}
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+### Link color
+
+Use the `.alert-link` utility class to quickly provide matching colored links within any alert.
+
+{{< example >}}
+{{< alerts.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+
+ A simple {{ .name }} alert with an example link. Give it a click if you like.
+
{{ end -}}
+{{< /alerts.inline >}}
+{{< /example >}}
+
+### Additional content
+
+Alerts can also contain additional HTML elements like headings, paragraphs and dividers.
+
+{{< example >}}
+
+
Well done!
+
Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.
+
+
Whenever you need to, be sure to use margin utilities to keep things nice and tidy.
+
+{{< /example >}}
+
+
+### Dismissing
+
+Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
+
+- Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript.
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}). The compiled version includes this.
+- Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
+- On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `
