Searching (P82)
Types
Strategies of searching
"Searching, is intend to find out what would match with the terms specified in the query, using different retrieval techniques", and "searching can be an effective retrieval method when the query is specific and the user knows explicitly what to look for" (Heting Chu, 2003, P82). Users favor the building block approach that uses single concept searches, and the snowballing approach that modifies the search query based on the result retrieved. In addition, lots of users just "quick/convenient" approach, by just type a single keyword or several term at once by leaving a space. Users can repeat this process until they find satisfied result.

Browsing (P87)
Types
Strategies of browsing
Browsing is seeking and selecting information by skimming, scanning, and other similar activities. People like to browse for getting information when a topic is not clearly defined, or finding information that is hard to specify explicitly, or choosing the right information among a mixture of relevant and irrelevant items (Heting Chu, 2003, P88).
Kowalski (1997) lists how people browse over search results they obtained.
(1). Browse by ranking. Users choice the search results that are presented in ranked order based on certain ranking algorithm.
(2). Browse by zone. The zone here refers to traditionally refined fields such as title as abstract.
(3). Browse by highlighted area. Those areas might contain information that people are looking for.
In Internet retrieval system, there are other two browsing types. ‘One is to browse by category, and the other is to browse by hyperlinks’ (Heting Chu, 2003, P89).
