Some will open links to content in a new browser window. Others return content in floating information boxes which can be sized, shared, docked, etc.

Usability can vary widely between selection-based search systems relying on a large number of variables. Even the most basic selection-based search systems will allow more of the web to be searched by the user in the context of their work than any one stand-alone search engine. On the other hand,

A key challenge for selection-based search is that a long or nested list of categories quickly becomes unwieldy for the user. Therefore, it is incumbent upon the selection-based search system to both categorize the user-selected text and to identify those online services which most naturally apply

In its simplest form, selection-based search enables users to launch a search query by selecting text on any application on their desktop. It is commonly believed that selection-based search lowers the user barrier to search and permits an incremental number of searches per user per day.

the process is sometimes said to be redundant if the system applies no intelligence to categorizing the selected text and matching it to an online service, and simply provides a link for the user to their preferred search engine(s).
