ones relevant to you.

8. Keyword Search Not Always Enough
Advantages
Speculative searching (i.e. Where are the best tacos in Houston?)
Finding general information (i.e. Address of Access Sciences’ website)
Disadvantages
8
Large result sets mean not enough time to read all documents
Noisy and irrelevant hits have to be filtered out
Narrowing the question may mean missing a key result
Have to type in all variants of a term
i.e. significant oil discovery, large oil find, >200M barrels???
