Advance search webpart not visible in SharePoint2013. Any one suggest what to do ?
Go to the Advanced Search page in the search center site. Edit the page and Export the Advanced Search Web Part. After saving the exported web part file to your computer, go to the Web Part Gallery in the top level Site settings. Click "Files" in the ribbon tabs and upload the file you just downloaded.
At that point, the Advanced Search Web Part should show up under the "Miscellaneous" group when inserting a web part a Team Site page. If you edit the properties of the Advanced Search Web Part file in the Web Part Gallery to have a group of "Search" then it will show up under the Search group.
