Articles & Reviews

  • Comparing Open Source Indexers Infomotions Musings; May 29, 2001 by Eric Lease Morgan
    Describes the history and features of eight open-source search engines, freeWAIS-sf (aging code and hard to install, but good for searching email and public domain etexts); Harvest (powerful gathering features for frequently-changing data stores, good with structured documents); ht://Dig (tricky to configure, no phrase searching, automatic stemming and match word highlighting); Isearch (weak documentation and support, easy to install, dated interface, Z39.50 support); MPS Information Server (zippy indexing of both text and structured data, Z39.50 support, Perl API, limited documentation); SWISH-E (simple to install engine, CGIs in Perl and PHP still beta, good for HTML pages, recognizes new META tags, sorts results by field; WebGlimpse (easy to install and configure, requires commercial version for customized output); Yaz/Zebra (mainly Z39.50, no Perl API, mainly a toolkit to index and respond to distributed client queries). Article also points out that chaotic information is less than helpful and encourages organization, structure and vocabulary control.
