1. 1 Engines for Multimedia Search Ran Hock Online Strategies

2. 2 Some Facts / Observations Different tools for different media. As with “Web” search, even for the same question and type of media, you may want to use more than one engine. Indexing is a problem – In some cases getting better, much better. Search “qualifiers” are often quite limited. Use the “big” services, but also take advantage of the specialized services.
