Metasearch Tools:
- Search several search engines or Web directories simultaneously,
eliminating the need to query each search tool individually
|
Metasearch Tools have limitations that include:
- Time-outs when search processing takes too long
- Displaying only 10-50 hits from each search engine they query (even
when many more results are available)
- Ignoring advanced search features from individual search engines
- Inability to employ Boolean and phrase searching
