+# Search Input
+
+`Component`, `Standalone`
+
+A minimalistic search input component that formats user query according to the provided fields.
+
+```html
+<app-search-input 
+    [fields]="['cm:name']" 
+    (changed)="onSearchQueryChanged($event)">
+</app-search-input>
+```
+
+> Notes: this component does not perform search operations.
+> It handles the user input, formats and produces the search query to use with `Search Query Builder` or other services. 
+
+## Properties
+
+- `fields` **string[]** - optional, a list of fields to use in the formatted search query, defaults to `[cm:name]`
+- `value` **string** - optional, initial input value
+- `label` **string** - optional, display label
+- `placeholder` **string** - optional, display placeholder
+
+## Events
+
+- `changed` **EventEmitter\<string\>**: emits when user presses `Enter` or moves the focus out of the input area
+
+## Examples
+
+```html
+<app-search-input 
+    [fields]="['cm:name', 'cm:title', 'cm:description', 'TEXT', 'TAG']" 
+    (changed)="onSearchQueryChanged($event)">
+</app-search-input>
+```
+
+In the example above, the search is performed against the following fields:
+`cm:name`, `cm:title`, `cm:description`, `TEXT` and `TAG`.
+
+The Search Input is going to produce the following results for user inputs:
+
+user types `test`  
+
+```text
+(cm:name:"test*" OR cm:title:"test*" OR cm:description:"test*" OR TEXT:"test*" OR TAG:"test*")
+```
+
+user types `*`  
+
+```text
+(cm:name:"**" OR cm:title:"**" OR cm:description:"**" OR TEXT:"**" OR TAG:"**")
+```
+
+user types `one two`
+
+```text
+(cm:name:"one*" OR cm:title:"one*" OR cm:description:"one*" OR TEXT:"one*" OR TAG:"one*") AND (cm:name:"two*" OR cm:title:"two*" OR cm:description:"two*" OR TEXT:"two*" OR TAG:"two*")
+```
+
+user types `one AND two`
+
+```text
+(cm:name:"one*" OR cm:title:"one*" OR cm:description:"one*" OR TEXT:"one*" OR TAG:"one*") AND (cm:name:"two*" OR cm:title:"two*" OR cm:description:"two*" OR TEXT:"two*" OR TAG:"two*")
+```
+
+user types `one OR two`
+
+```text
+(cm:name:"one*" OR cm:title:"one*" OR cm:description:"one*" OR TEXT:"one*" OR TAG:"one*") OR (cm:name:"two*" OR cm:title:"two*" OR cm:description:"two*" OR TEXT:"two*" OR TAG:"two*")
