Visualizing overlap and rank differences among web-wide search engines: Some free tools and services |
| abstract |
Purpose - To compare the performance of different search engines, highlighting the overlap and rank differences. Design/methodology/approach - Presents results of an overlap test search series among traditional CD-ROM indexing/abstracting databases since the mid-1980s, web databases, and authors' own polysearch engine, and reviews Google Scholar. Findings - Finds that overlap is minimal among web-wide search engines which crawl and index the mostly unstructured open web; and that overlap among Google Scholar and the native search engines is far less than the ideal 100 per cent in the optimal context of crawling and indexing highly-structured and metadata-rich collections. Originality/value - Reinforces the existing view that for comprehensive searches one must search more than one database. Highlights and recommends several very good search engine sites. |

Design/methodology/approach - Presents results of an overlap test search series among traditional CD-ROM indexing/abstracting databases since the mid-1980s, web databases, and authors' own polysearch engine, and reviews Google Scholar. Findings - Finds that overlap is minimal among web-wide search engines which crawl and index the mostly unstructured open web; and that overlap among Google Scholar and the native search engines is far less than the ideal 100 per cent in the optimal context of crawling and indexing highly-structured and metadata-rich collections. Originality/value - Reinforces the existing view that for comprehensive searches one must search more than one database. Highlights and recommends several very good search engine sites.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Emerald Fulltext Archive Database 1994-2005</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Information retrieval</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Search engines</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Search output</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">Online information review</subfield><subfield code="d">Bradford : MCB Univ.
