Online Searching:

The real difference between manual searching and online searching lies, according to William A. Katz, in the mechanics and the jargon of the latter. However, after doing a number of searches, one becomes proficient in searching databases online. In short, it is practice that makes one perfect in the art. Besides, each international information service has brought out its user guide which helps attain mastery over, what Katz calls 'mechanics'. Online searching is particularly helpful and resorted to when (i) depth search is involved, and (ii) exhaustive search is called for. Yet another merit of the online searching is the facility it offers of using Boolean logic which allows limiting or expanding the search as required Because of the three logical operations symbolised by OR, AND and NOT, it is possible to co-ordinate the relevant terms by modifying the search strategy. The online search, unlike the manual search, ensures at once enhanced, quick and refined access.
