Before search engine optimization, could we talk about search engine construction ? The simpliest one I've found reads a whole of html files of a web site, and stores in a text one 4 lines per read file
1 for the path;
1 for the title;
1 for the description;
1 one for the strip_tagged text.
The search engine compares key words sent by a form with the content of each line and scores 2 hits for a matched word in the title and 1 hit for a match in the text.
I modified this to store its infos in a sql dbase, and to extract them again.
My indexator/search engine still does'nt follow hyperlinks.
My tables are not indexed (dbms sense).
I read an interresting article on zend's homepage about search engines... but not much technics.
