Why do personal site search engines suck?

[ªXe]

Yes, you are very right. And thats because we dont give a lot hard work for our code on search engines.
It can be over come by adding exact tags as required, and using those tags in our search engines database. But it wont work for forums. For forums, it should be correct use of words in Headings or Topic heads.
personal websites are made with an expectation that ppl will come from google, friends, or other friends site,. Visitors will read, visit archives, other topics in side bar if they see anything interesting or/and leave. Because of this pattern, personal sites builder rarely make or give a lot effort in coding accurate code for search.

Ppl with huge websites have guarantee that ppl will use their search bar, so they give a lot effort for their search engines to give accurate results.
