Comparison and Evaluation on search effectiveness
Characteristics that make all 3 search facilities similar or different from one another
• Database
• Speed
Strength & Weakness
The number of searches with subject directory and meta search engines are far narrower than search engines. However, with lesser hits, the meta search engine is very specific in their search which is efficient. Unlike the meta search engine, subject directories are inefficient as the database that they have is very little as compared to other search engines.
Overall, I would choose meta search engine if I want a precise search and a normal search engine if I want a large variation.
