The field of law contains a huge amount of information which may be to some degree relevant to any given problem. However, because of the large amounts and unintelligence of search engines, the time required to find relevant information grows proportionally with the amount of legal content. If, however, all materials are classified into searchable subjects, the efficiency may be improved.

Using a general search engine is generally a complete waste of time, as the contents indexed by those contains legal and non-legal information, and even apparently legal information can be very unreliable unless the source can be determined to be reliable.
