It's all about the way the wordex is maintained. I worked at Verity for a couple of years, and most search engines work the same way as theirs ... They build a huge inverted file with the format :-
word docid,ofset docid,offset docid,offset
word2 docid,offset docid,offset

etc ...

Then to find relevant docs the search for word, and there are the docs and the offset to the beginning of the word for each ocurrence in the document The offset is primarily used to check proximity between words in multi-word queries, provide relevance ranking for scoring the search results etc. but one of the eye-candy spin-offs is that it provides the offset in bytes to the point where you can put a <span class=something tag ... and then find the next space, and put a </span> tag ...

Simple if you actually write your own search engines ...

Oh ... I forgot to mention ... docid is a unique key pointing to records in a metadata database containing such things as the doc description, last update, last spidered, summary, url, system location, language etc. etc. etc. ...

Go to thunderstone - http://www.thunderstone.com and get yourself their free version of webinator - it does everything "out-of-the-box" and the freebee will handle 10,000 documents.

as this thread is about the highlighting </whisper>

... and the span tag's class does the colour/emphasis highlighting of the search term ...

I think I answered both of them in one go
