+Set up searchable paths with regular expressions. If no test expression is provided it will search on all paths. Considering you have this structure:
+
+```bash
+docs/
+├── .vuepress/            
+│    └── ...
+│
+├── master/               
+│    └── ...
+│
+├── 1.0/               
+│    └── ...
+│
+└── 2.0/               
+     └── ...                       
+```
+
+You can set up searchable paths with `test` as:
+
+- RegExp: `'/1\.0/'`
+- Array of RegExp: `['/1\.0/', '/2\.0/']`
+
+
+Otherwise,  the default search will return duplicates, once you can have similar content between folders `/master/`, `/1.0/` and `/2.0/`.
+
 ## Tips
 
 ### Tweak the default colors.
